The same argument could be applied to the GPRS architecture.  Gluing
additional access technologies to the P-GW with GTP tunnels is completely
unnecessary.

We should definitely not try to replicate GPRS with Mobile IP.  I think the
point of this discussion is that some of the requirements (like IP address
continuity throughout all space and time) that drove the existing architecture
need to be relaxed.

I think we may be close to that point already.
