That's the goal here? To ensure we'll never have another protocol
transition? I hope you realize what a flawed statement that is. We can't see
into the future. However, assuming that IPv6 is the Last Protocol seems a
bit short sighted. If we get 20 years out of IPv6, that will be just peachy.

Of course, if we can't get PI address space for enterprises and real
multihoming, there won't be any real IPv6 deployment. Lots of (possibly
illegitimate) IPv4 trading and NAT, but not IPv6.

These aren't nice to haves. Even if it shortens the life of IPv6, that is an
acceptable trade-off.

IPv6 is not the Last Protocol.
