Collaboration Awareness in Support of Collaboration Transparency: Requirements for the Next Generation of Shared Window Systems

Window layout: is it necessary to have shared control of it? We might define instead a shared space where the window looks at. Windows inside this shared space may share the control and layout, but the main window should not be shared because at the user interface, there are other private windows that also compete for screen space and the other users cannot see.

What if only user A has the application, but still desires that user B sees what is going on? In this case, either the whole application is sent to B (with the networking and copyright issues associated with that) or B cannot see what going on at A screen. A hybrid approach between central and replicated application might overcome these limitations.
