Daniel,

The point is that unless we are collectively foolish, IPv6 will
not have a disaggregation problem - it starts out classless
and provider-based, and dual homing will in the end be solved
by dual prefixes. I really can't see why we would *need* prefix
length based discrimination as we do for IPv4.
