Yes, our RTSP server implementation supports multicast streams.  This 
is demonstrated in the various "test*Streamer" demo applications. 
E.g., You can demonstrate this by uncommenting the line
//#define IMPLEMENT_RTSP_SERVER 1
in "testProgs/testMPEG1or2VideoStreamer.cpp".

Yes.

No, because that is a silly idea.  It's the role of the server, not 
clients, to choose whether - and with what address/port - a stream is 
multicast.  See

No.
