[vlc-devel] SIP for VLC

This is a bad idea, because there are no IETF 
standards right now for doing this.  At present, 
the IETF standard protocol for IPTV/VOD-type 
service is RTSP (for setup and control) and 
RTP/RTCP (for data).  Therefore, you should use 
RTSP/RTP/RTCP, as implemented already in VLC (and 
many other products).

There has been some talk - within the IETF - 
about possibly defining and standardizing some 
sort of hybrid protocol that combines SIP (for 
setup) with RTSP (for control (including 'trick 
play')), and still using RTP/RTCP for data. 
However, until this happens, it's definitely not 
something that you should try to fudge yourself.
