Hi Abhijit,

I think it would be good to just use TCP for our application protocol.  
Topology wise, I think we should do like AbiWord does.  That is, we 
have a "leader" and everybody connects to the leader.  The leader will 
then parse the messages, optionally process them, and rebroadcast them 
to all the other clients.

Initially, the leader can probably be the person who 1st shared the 
activity.  But if that person disconnects, or their computer looses 
power, we need to change the leader.

We probably can't use the socket module directly, as we need Glib 
mainloop integration so we don't block the ui.  GLib will take a file 
handle and give us a mainloop IOChannel via this api [1].
