For what (little) it's worth, there are existing implementation of TCP-
over-UDP. I found
http://thebends.org/~allen/utunnel/
http://www.jankratochvil.net/project/tcpoverudp/
http://www.vergenet.net/linux/iproxy/iproxy_paper/stuff/iproxy_paper.pdf
http://code.google.com/p/tcpoverudp/
So we have several implementations *before* an Internet draft :-)

I am not religiously against running UDP between peers :). However,
based on reasons stated earlier, I think that RELOAD base draft of
the P2PSIP WG is the *not* right place to insert a reliable
congestion control protocol. It is easy to get these protocols wrong
than right. We should not abandon well designed TCP stacks so easily.
As a practical insight, Skype application will not connect to the
Skype network if it cannot establish a TCP connection with a Skype
super node.
For those who want to run UDP, I totally agree with your idea of use
RFC-XXXX for a TCP-over-UDP protocol.
I want to keep our focus on the issues of P2PSIP protocol such as
configuration, security, and overlay maintenance.
