CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is related to concurrently filed, commonly assigned, and co-pending U.S. patent application Ser. No. 10/857,254, entitled “DYNAMICALLY ADAPTABLE COLLABORATIVE ELECTRONIC MEETING SPACE,” the disclosure of which is hereby incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates, in general, to collaborative electronic meeting space, and, more specifically, to an additional meeting canvas accessible only by meeting presenters. 
     BACKGROUND OF THE INVENTION 
     The first Internet was a communications system funded and built by researchers for military use. This Internet, originally known as ARPANET, was embraced by the research and academic communities as a mechanism for scientists to share and collaborate with other scientists. This collaborative network quickly evolved into the information superhighway of commerce and communication. The Internet explosion was due, in part, to the development of the World Wide Web (WWW) and graphically-based Web browsers, which facilitated a more graphically-oriented, multimedia system that uses the infrastructure of the Internet to provide information in a graphical, visual, and interactive manner that appeals to a wider audience of consumers seeking instant gratification. 
     As the technology underlying transmission bandwidth has grown in conjunction with the accessibility to such increasing transmission bandwidth, a new paradigm for the old idea of Internet collaboration is emerging that takes advantage of the modern graphical, visual world. This new paradigm is also driven by the advance in real-time or time-sensitive data transmission technology, such as Voice over Internet Protocol (VoIP) technology, and the like. Non-Internet videoconferencing, which has generally never been able to completely supplant teleconferencing as a viable means for reliable communications, is slowly fading away in favor of Internet-driven technology, such as collaborative electronic meetings. Services, such as WEBEX COMMUNICATIONS, INC.&#39;S, WEBEX™ electronic meeting or collaboration services offer the ability for users to connect, at least initially, across the Internet to share voice, video, and data in real time for meetings, presentations, training, or the like. 
     In such collaborative meeting environments, a virtual meeting room typically is made up of several meeting objects which are generally containers for presentation information, such as slides, video, audio, documents, computer applications, and the like, that are themselves contained within the container of the meeting room. These meeting objects are typically placed into a static arrangement on the actual electronic meeting interface. Therefore, chat objects may be set on the bottom right of each meeting interface screen, while slide or other main presentation objects are set on the left half of each meeting interface screen. Meeting presenters usually enter the electronic meeting room shortly before the meeting to prepare the various objects with data, such as slides, animation, data, or the like. Once the meeting begins, each of the meeting participants, both presenters and viewers, see the same static meeting interface with the presenters information loaded thereon. 
     In some versions of current electronic meeting applications, a presenter may be able to layer different presentation or meeting objects that may be uncovered or hidden by selecting tabs. However, from meeting to meeting, the arrangement of the various meeting objects will be the same or similar with all meeting participants viewing the same meeting set up. The presenter will typically not be able to add anything to an ongoing meeting except through a live screen share or other such facility. Moreover, in a large meeting where there may be multiple presenters, if one presenter needs to communicate with another, the existing meeting interface would need a chat object that allows a user to select the individual participants in order to effect that communication. If no chat object existed, it would be more complicated for one presenter to communicate with another. 
     BRIEF SUMMARY OF THE INVENTION 
     Representative embodiments of the present invention are directed to a collaborative electronic meeting system that provides an additional presentation canvas surrounding the active meeting canvas that is only accessible by a meeting presenter. Using this presentation canvas, additional meeting objects may be used by the presenters or even created and staged by the presenter to be dragged onto the meeting canvas for use during the active meeting. The meeting participants who are not presenters may not view this presentation canvas or any of the objects located thereon.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1  is a screen shot of meeting canvas  10  illustrating active scene  100  displayed to the observing participants of a collaborative electronic meeting. Meeting canvas  10  includes podium object  101  that is displaying the video and audio from a camera, quiz object  102  that provides an interactive quiz to the observing participants, and slide show object  103  that presents a slide show in a presentation document format, such as MACROMEDIA INC.&#39;s MACROMEDIA FLASH™, MICROSOFT CORPORATION&#39;s POWERPOINT™, or the like. As the electronic meeting proceeds, the observing participants interact with and view the various meeting objects within scene  100 . 
       FIG. 2  is a screen shot of expanded meeting canvas  20  that includes presenter canvas  200  surrounding scene  100 . While the observing participants view only meeting canvas  10  as illustrated in  FIG. 1 , each meeting presenter views expanded meeting canvas  20  which is essentially meeting canvas  10  ( FIG. 1 ) expanded by presenter canvas  200 . Presenter canvas  200  also includes meeting objects that are only visible to or interactive with other meeting presenters. Presenter canvas  200  includes presenter list object  201  that lists each of the presenters in the electronic meeting, presenter chat object  202  that allows direct chat communication between the presenters, and scene tabs  203  that allow the presenters to control the electronic meeting by activating any additional scenes that have been created for that particular meeting. The various meeting objects displayed on scene  100  continue to operate normally in expanded meeting canvas  20  during the electronic meeting. The display of scene  100  is adjusted in expanded meeting canvas  20  to make room for presenter canvas  200 . Other than the resizing or moving, scene  100  is the same. 
       FIG. 3  is a screen shot illustrating expanded meeting canvas  20  that is staging new meeting object  300  for the electronic meeting. The interaction that occurs within presenter canvas  200  remains hidden from the observing participants view. Therefore, presenter canvas  20  allows each presenter to modify or create new meeting objects outside of the view of the observing participants. Once created or modified, the presenter may stage the meeting object on presenter canvas  200  until he or she is ready to bring it into the active scene. 
       FIG. 4  is a screen shot illustrating new meeting object  300  that has been added to scene  100 . To add the staged meeting object, the presenter needs only to drag it into the scene. Thus, the presenter dragged new meeting object  300  from its staging location on presenter canvas  200  ( FIG. 3 ) to the new location illustrated on scene  100  in  FIG. 4 . 
       FIG. 5  is a screen shot from an observing participant illustrating new meeting object  300  on new scene  400 . Once new meeting object  300  is dragged onto new scene  400 , all of the meeting participants, whether merely observing participants or presenters, may interact or view the object. In the example illustrated in  FIG. 5 , the observer participants may be able to interact with new meeting object  300  to fill in data for an application connected with the electronic meeting. 
     The ability of a presenter to view a different meeting canvas than the browsing participants is made possible by an interactive multimedia communication server (iMCS) hosting the electronic meeting. An iMCS operating an electronic meeting application configured according to one embodiment of the present invention is capable of maintaining separate communication streams connected to the same electronic meeting for each meeting participant, including meeting presenters and meeting viewers. The iMCS transmits the communication streams for meeting canvas  10  ( FIG. 1 ) to each of the current observing participants. However, the iMCS also allows a separate communication stream to be sent to the presenters that results in expanded meeting canvas  20  ( FIG. 2 ). When a presenter interacts with objects with the additional presenter&#39;s canvas, the data streams connected with those become separate links to the iMCS, yet still integrally related to the electronic meeting. When a presenter drags something from the presenter canvas onto the regular, active scene, iMCS adds the data stream supporting the object to the data stream for the active scene when it removes that data from the separate presenter-only data stream. One example of such an iMCS that includes the capabilities described above is MACROMEDIA INC.&#39;s FLASH COMMUNICATION SERVER™ (FCS). When implemented in the FCS, the client-side of the electronic meeting may be presented to the participants using MACROMEDIA INC.&#39;s MACROMEDIA FLASH™ player. 
       FIG. 6  is a block diagram illustrating electronic presentation  60  configured according to an additional embodiment of the present invention. Electronic presentation  60  is hosted by host server  600  running the server-side portion of an electronic meeting application. The software code disclosed herein (e.g. for performing the operations for presenting electronic presentation  60 , determining the meeting participants having presenter rights, and presenting the additional presenter canvas to those participants having presenter rights) may be stored to a computer-readable medium, as is well-known in the art, such as being stored to host server  600 . As those of ordinary skill in the art will readily appreciate, such computer-readable medium may comprise, as examples, a hard disk, floppy disk, optical disc, etc. Multiple users, reflected by meeting participants  602 - 607 , each run a client-side portion of the electronic meeting application that communicates with the server-side meeting application on host server  600 . During electronic meeting  60 , the data streams for the active scene are communicated between host server  600  and meeting participants  602 - 607  over Internet  601 . Some of meeting participants  602 - 607  are meeting presenters and some are merely meeting observers. For purposes of this hypothetical example, meeting participants  603  and  607  are presenters. Thus, in the present embodiment meeting participants  603  and  607  receive additional data from host server  600  which instructs the client-side portions of the meeting application to insert the presenter canvas including any meeting objects or pods that have been defined for the presenter canvas. 
     The data or input streams from host server  600  that feed the objects in the presenter canvas are maintained separately for the presenters, meeting participants  603  and  607 . If either one of meeting participant  603  and  607  drags a meeting object from the presenter canvas onto the active scene, host server  600  adds the data streams for those objects to the data streams for the active scene. Thus, the active scene is changed during the electronic meeting. 
       FIG. 7  is a flowchart illustrating example steps that may be executed in implementing one embodiment of the present invention. In step  700 , presenter rights are assigned to selected ones of a plurality of meeting participants. An meeting scene is displayed to the plurality of meeting participants, in step  701 , where the meeting scene has at least one meeting object arranged on it. In step  702 , presenter workspace is added around each meeting scene that is displayed to one of the selected ones with assigned presenter rights. One or more meeting objects are rendered on the presenter workspace, in step  703 , wherein access to the meeting objects is limited to the selected ones with assigned presenter rights. In step  704 , data feeds for the meeting objects on the active meeting scene are maintained separately from the data feeds for the presenter workspace. In optional step  705 , one or more of the meeting objects on the presenter workspace may be moved to the active meeting scene. In response to the moving, the data feeds for the moved meeting object are associated with the data feeds for the meeting objects on the active scene, in optional step  706 . The moved meeting object, along with the other meeting objects, are then displayed on the active meeting scene, in optional step  707 .
