Instant messages can only be sent to users logged on to Sametime Server using either the Notes client or the Sametime Connect client, and who indicate they're willing to receive instant messages. You'll probably find this informal messaging is great for improving communication within workgroups in which some members are physically isolated, such as those in different buildings or cities. Users can also use a browser or other client to check Sametime Server's database of scheduled meetings.
Authorized users can schedule meetings, and the scheduler can control who participates.
When a user joins the meeting using a Web browser, the Sametime Server downloads a Java applet that provides the real-time conversation features. Once in a meeting, users can doodle on a shared white board, share an application, or use Microsoft's NetMeeting for real-time chatting. This is a handy feature, excellent for revising documents. The features worked reliably, and with little load on the Sametime Server. Like all remote-control applications, updates were jerky and unpleasant to view.
