Ah, I misunderstood your earlier statement -- "I am really interested in preserving identity over [SIP networks today with intermediaries that modify SDP in transit]" -- to mean that the intermediaries were not to be modified. So we're really both talking about SIP networks for some upcoming tomorrow, not SIP networks today.
Good. I think that leaves a lot of common ground to work with. /a
