  Ah, that's the rub.
  Getting multihomed IPv4 connectivity is a lot harder than getting IPv6.
  (Believe me. I've been involved in getting the groundwork layed in place at
multiple mid-sized regional ISPs in order to convince the powers-that-be to
allocate an AS#)

  In my talking with these ISPs, they see essentially no reason for them to
risk any of their network to deploy IPv6. Particularly since 6to4 lets their
customers do it whenever the customer wants. The customers mostly do not care
about IPv6 either, but they wish they could multihome themselves easier. Most 
have multiple xDSL and 10Mb ATM VCs, but have all sorts of hacks to permit
them to make the most use of the bandwidth and redundancy.

  This is why I object to any solution that has different classes. Nearly
every single one of these ISPs went from stack of {SCO,Solaris,Xylogics,BSDi}
and modems plus T1 to OC-3+,etc. The customers went from "soho" operations
with a single high-end Sparc 2 or 486 to racks and racks of equipment. I
think that this is the story of the rest of the Internet as well.
