What keeps being overlooked here is that the concept of a global DFZ is
artificial, and was originally specifically intended to sort out the players
who could afford serious routers from the rest. There is no technical need
for every organization to know the gory details of every other organization,
the basis for maintain the myth is purely an ego driven desire to be
considered a peer.

That was good work looking at the alternatives. I have also been maintaining
one without ties to political entities, currently
draft-hain-ipv6-pi-addr-09.txt. At the end of the day we need to revisit the
assumption that the only viable aggregation unit is provider based. There
are trade-offs here, and with a small shift toward structured topology we
could put a lid on the routing table problem.
