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?
These are my opinions, not necessarily my employer's. I hate spam.
