WebRTC applications are the primary beneficiaries of this proposal, which
is why I submitted it here. I can certainly send it to BEHAVE if that's a
better fit. (Depending on how closely this references
draft-reddy-behave-turn-auth, that might be a good indication of where this
should end up.)

RFC 5766 mandates the use of the long-term credential mechanism. One of the
goals of this proposal is to work with existing TURN servers, so it also
uses the long-term credential mechanism, the key point being that the
vended credentials have finite lifetimes.
