Carrying the "PI address" scheme of multihoming (i.e. assign a globally-
visible prefix to anybody who wants to multihome) from IPv4 to ipv6 is the
best way to ensure that it will happen again. And there are a lot more
potential ipv6 prefixes than IPv4 prefixes.

The IETF's position on this matter is that shim6 is the answer. My view,
that an ID/LOC split is a fundamental requirement for scalable multi-
homing, is considered heretical among the IETF leadership. Please don't
confuse anything that I write with an IETF position because the two couldn't
be more differeent.
