What about "Jingle multicast" in MUC?
Scenario: a MUC participant want to initiate a session with every another participant: he can send a file, initiate a voice or video session, or any non-XML, binary stream.
Each one partipant can accept or refuse.
Each Jingle event (beginning, end, a user quits, etc.) can be notified to the chatroom.
