This will break the main ICE-TCP mechanism (IETF draft-ietf-mmusic-ice-tcp).
I am not aware of any application using this _as_of_now_. Probably too many
NAT and firewall implementations will reject it already. And then, some TCP
stacks reportedly do not support it (e.g. Windows before Vista).
On the other hand, if someone were to tunnel/encapsulate TCP over UDP, this
could actually be useful - think about peer-to-peer NATted-to-NATted file
transfers for instance.
