I'm behind on this thread, but I thought that multicasting was already worked out -- the SDP contains the multicast address the sender will send to, and the listeners will listen to, and specifies that it's a one-way audio link. Of course, it's a bit messier to get the INVITE to the UAs that it should, but that's pretty much a matter of forking. (The big packet load is going to be the audio; getting the INVITE out is a minor matter.)
