Like http://tools.ietf.org/html/draft-thomson-rtcweb-ice-dtls-00 ?

Yeah. It doesn't actually reduce round trips here because you still want to
confirm consent before doing the whole proof-of-possession thing. If you
don't care about the associated DoS vector (and we might not need to worry
about that if you can validate the ClientHello properly), a 1 round trip
handshake would be very fast.
