No, I won't be doing this, because RTSP-initiated streaming via 
raw-UDP is *not* a standard, and I do not want to encourage its use. 
Our server supports it only because one non-standard, but popular 
client (the Amino set-top box) uses it (but cannot handle standard 
RTP-over-UDP streaming).

Please DO NOT deploy any RTSP client products that request streaming 
via raw-UDP.  As I noted above, this is NOT a standard.  (The Amino 
set-top boxes work by misusing the RTSP protocol in ways which were 
not intended, and which have not been well-documented.)

Raw-UDP streaming can work only for data types (such as MPEG 
Transport) that contain their own, embedded timestamps, and prevent 
the use of standard RTCP-based techniques for measuring QOS, 
requesting retransmission (for reliability) etc., etc.  I would like 
to see it die eventually.
