So here's some RTP/RTSP stuff I've found in random order.
|RAT||Looks interesting, haven't tried it yet; does conferencing, not sure if it's suitable for just listening|
|PulseAudio||formerly known as polypaudio (change is good!) in the FAQ claims to do some RTP/RTSP stuff, haven't tried it yet|
Well back to this later...
