I'd love to see an IETF draft on how this technology is applicable, because I'm failing to follow your logic as to how VISA/MC are in any way related to global routing infrastructure. As far as I can tell, they are good at building a database that can rapidly validate lots of fixed-length numbers (which, I might add are rigidly hierarchical through ISO standards and therefore easier to break up the namespace to do efficient searches).

You're certainly entitled to your opinion, but it's simply not helpful to this discussion to try to blame another deep pocketed, greedy corporation for preventing everyone's refrigerator from getting a /32. This isn't a giant conspiracy. IPv6 route scale is a hard problem to solve, and it *IS* a reality for every major ISP, even if you put aside debates about the relative scarcity or lack thereof of the address space that exists in IPv6.

For what it's worth, I am against this proposal as written. I think it has some good ideas, but I don't support the linking to existing IPv4 address allocations, nor do I like the idea of having significant amounts of renumbering triggered every time a given block size is exhausted. However, some of the other requirements might make sense in making the "Open access to IPv6" policy more palatable.
