Shared Event Model of Collaboration?
So if all clients want exactly same view at all times, then the “shared event” model is a waste.
Might as well, just share the display produced on originating client (cf. Microsoft NetMeeting)
In fact, shared event typically enables each client to get the same view but instead one shares the object but has different presentation layers on each client
For instance, share a single XML document but apply different style sheets on each client
Again in command and control, basic application is a 3D map (Geographical Information System) but not so interested clients can present a simple 2D view
