The ability to have a well-known UDP port on which tunnelled DCCP connections can be accepted seems important to me; as does the ability to run a server accessible via UDP and native DCCP listening on the same port, also accessible via tunnelled DCCP. Neither of these are possible if we use only the outer UDP ports. Fair point. The latest discussion started to wander off from discussing the benefits/disadvantages of using the UDP/IP 4-tuple instead of 6-tuple, but I don't recall anyone really opposing the 6-tuple text. Is someone strictly against the 6-tuple model, or do we have rough consensus of sticking with the current text in the draft? (with editorial changes as suggested in earlier mails) - Pasi
