Problems with removing NAT from a network

Relay nodes are always protecting themselves by rate-limiting, aren't they?
And isn't most media traffic relayed? I'm not seeing how the NAT64 scenario
would *dramatically* increase Skype's global relay traffic. NAT64 would
currently be a very small percentage of all Skype traffic.
We can always find examples of where things will break with v6. While the
v6-only world is still very small, let's *start* somewhere, where
intelligent clients like Skype can always "fall back" to v4. Lots of time
to figure out the corner cases.

Skype can still make this work by relaying, but in order to protect the
relay machine's bandwidth it will rate-limit the traffic, and so your
A/V experience will suffer. And that's assuming there's enough
dual-stacked relays... if there aren't, it won't be possible to find a
relay that they can reach over IPv4 and you can reach over IPv6 that has
