anyone still not paying attention? (read the CERNET2 reports on the costs of dual-stack...) Native may be your best long term bet.

That is a point I have made with people at times, too. If you are struggling holding the current table of 32-bit routes, what is the addition of a bunch of 128-bit routes going to do? Full routes dual-stack is going to hurt people in a lot of places. This was another reason for aggressively reclaiming unused IP addresses without issuing any new, it would reduce the extent to which v4 could continue to frag. It will be sort of like a bulge moving through a snake for a while as the v6 table begins to grow with multihomed /48's and the v4 table also grows with increased fragmentation. And "Katy, bar the door" if they take away the multihomed restriction for GU /48's.
