If a nearby conversation sounds interesting, the user can easily move to join that group and focus on them. For users with less bandwidth, audio and video services can be tailored accordingly, and, if desired, text chat can be used for participant interaction. The session manager supports a grouping metaphor which allows the creation of hierarchical sub-sessions. Sub-sessions can be expressed at the application level as tables, rooms, etc. The rules of interaction between sessions, users, and objects are governed by a flexible policy mechanism.
Application developers can create their own policies deterring how session entities interact.
A Virtual club has also been created which provides access to a variety of virtual club rooms, e.g. a sports room, music room, etc. The initial three clubs utilize a similar application interface and table metaphor and differ primarily in the event which is streamed to the club and tables. Other possible applications include virtual town meeting, virtual bleachers sports club, e.g. watch college basketball with your alumni friends, virtual game club, virtual morning call, an application for stock analyst's morning briefing etc. A video of the Virtual Jazz Club, which includes a distributed karaokee session, can be found by following the jazzclub link. The current virtual clubs utilize the iCV video conferencing system which includes a Pro version which offers a video capture card capable of transmitting and receiving broadcast quality video and supports up to 20 simultaneous video streams.
