Sometimes I wake up in the middle of the night asking myself whether an
RTP-light would be feasible, without multicast support, without mixers,
without SSRC, CSRC, but instead with a timing model that fits the needs
of modern video codecs (that decouples sampling/presentation time from
transmission time).  Multicast is nice, but IMHO for niche applications
(only).

multipoint video conferencing system that uses IP multicast and RTP.)
