Agreed. And (perhaps to Brian's point just now), it may not matter all that much which one "wins." At some point having a solution is more important than having the best solution (especially since best is usually quite subjective). What we need is one good-enough solution for IPv4 over IPv6 communication to be anointed THE suggested IPv4 over IPv6 mechanism so that operators have something to deploy. Today they have a research project to even discover what the options are - and this is not how technology gets widely adopted in my limited experience.
