port pairs for a single Virtual Venue? Why do they not share a
single IP/Port address? Doesn’t the payloadtype field in RTP
allow you to effectively discern between audio and video streams?</span></font></li>

allocation of a block of multicast IP addresses from Internet2. Since
multicast traffic is scoped purely on IP address and since the amount of
traffic associated with a Virtual Venue would generally degrade any other
multicast application sharing the same IP address but using a different port, it
seems to me that each venue should have a dedicated single IP address.</span></font></p>

there anything wrong with following the RTP default ports of 5004 for RTP
traffic and 5005 for RTCP traffic?</span></font></li>
