It would probably be a good idea to have RFC6544bis. We can also use this
draft to define TLS ICE candidates.

One question I wanted to ask is do we need to maintain the same scope to
ICE TCP candidates? Do we really need simultaneous open TCP candidates? Are
there any plans of using TCP candidates to directly connection two end
points behind NAT or is it only going to be used in scenarios where one of
the end points is on the public IP? I think based on current usage patterns
RFC 6544 can be greatly simplified.
