Thanks Roni.

For the port mapping, I believe mmusic should be cc'ed as this work was presented there as well.

Here is the current draft:
http://tools.ietf.org/html/draft-begen-avt-ports-for-ucast-mcast-rtp

Here is an alternative proposal that is not in the draft yet:
ftp://ftpeng.cisco.com/abegen/Receiver-Driven_Cookie.pdf 

Also see the email for an improved version of the method that is currently proposed in the draft above:
http://www.ietf.org/mail-archive/web/avt/current/msg12232.html

Comments are much appreciated.
