True, I didn't read it. Thanks.

Why do you thing so? Of course I want it. I was just asking a
question, no more. ;)

Which is the reason for it? do you mean those routers that "sometimes"
behave as symmetric NAT router and other times not? Or perhaps you
mean that even in a normal and correct router (not symmetric NAT) STUN
would not work on 100% of cases?

Well, AFAIK ICE is very far from being interoperable, isn't it?
And TURN requires RTP through a media proxy, that is not a very
scalable solution :(

Thanks for your reply and thanks for your work :)
