Hello, I won't publish my SIP URI in a phone book allowing anyone to see it. We already agreed on that. I'll tell it to people that I know only. I'll tell it using a user friendly mechanism called "pairing" : We meet each other with our cell phones, and agree to exchange our contact information. So, the procedure is under our control. Pairing is good for us also because it allows us to exchange a secret key (note that this is already enough motivation for the pairing idea). The point is that, if I give you my SIP URI (using the pairing procedure) then I can also give you my Mobile IPv6 home address using the same pairing procedure. In other words, there is _no more resolution_ from SIP URI to home IP address. You get them **concurrently**. We have each other's SIP URIs and home addresses. ->SIP application is happy, it has the target SIP URI. ->Routing problem is solved by mobile IPv6. My question was: do we need the SIP trapezoid in this case.
