I think so (e.g., the example in section 14.1 in the RTSP 
specification).  However, I don't think I've ever seen such a stream 
(where the server expects the client to issue RTSP "SETUP" and "PLAY" 
commands, without having first done a "DESCRIBE"), and the LIVE555 
library doesn't currently support this anyway (because it currently 
sets up a connection to a RTSP server only when doing a "DESCRIBE").

>What if the SDP contains a UDP source

Remember that the data delivery protocol (RTP/UDP or raw UDP) is 
independent of the control protocol (RTSP).  RTSP authentication - if 
any - is done the same way, regardless of which data delivery 
protocol ends up getting used.
