Yeah, you're right of course, this needs to be dealt with somehow.
cut+paste: maps nicely to a number of different buffers. Would need
some policy, and the session agent becomes closer to a buffer manager.
resolutions: again policy, perhaps have a master client, or if none
defined let the last or just the first choose. Not sure.
But these issues don't need to be solved now, do they?
