Once I understand the TeaTime stuff a bit better (JUST a "bit") it 
should be possible to share literally any kind of updates p2p between 
squeak/cobalt plugins. All TObjects have connections to the TeaTime 
collaboration architecture built into them and if I'm reading the wiki 
correctly, teatime is actually responsible for updating the local object 
as well as the remote clients, so if it works properly with the local 
drawing board, it should with 2 people. And if it works with 2, it 
should with arbitrary n once they establish a connection. I think it 
automatically shares the current state of the object upon login, so 
everyone should literally be on the same page, after the connection is 
established.
