Pastry and IRIS look interesting, I'll check it out. Your absolute right
about Jaber and the server requirement. Our hope was that there would be
enough Jaber servers around that most people wouldn't need to go to the
trouble to set up and administer one. Jaber would provide presence and
allow us to pass small messages between peers, large transfers would
happen out of band directly between peers.
