I agree, Teredo looks interesting. I think there are several advantages 
over ICE.

*) IPv6 compatible, and makes it transparent to the client if the peer 
has a native IPv6 address, or uses 6to4 or Teredo.

*) Takes advantage of IPv6 today by using IPv6 for services which need 
peer-to-peer communication, which makes migration to native IPv6 smoother.

*) Miredo, a Teredo software for Linux and BSD, will be part of the soon 
to be released Debian 4.0, and probably several other Linux 
distributions. It's already in FreeBSD ports tree (and of course Debian 
testing).

*) IPv6 and Teredo is installed and enabled by default in Windows Vista.

*) Teredo supports both UDP and TCP, and other protocols as well.
