I'm missing a key idea.

Some activities have persistent data, say a document.  Another example would 
be the high score database for a game.

That data has to live somewhere and/or somebody has to own it.  You can put 
it on a server, or one of the users can act as the server, perhaps the one 
who initiates the shared activity.


I think another example that was discussed recently was viewing a batch of slides.  One proposal was that the other users only loaded the page they were interested in.  I think that leaves the initiating user acting as the server.


Are there two types of sharing, one with persistent data and another without?
