In the IETF meeting in Toronto in which the IETF formally settled on IPv6, I
recall someone (in the IPng directorate meeting) making exactly that point -
that IPv6's strongest competitor would be IPv4, and they furthermore
predicted that IPv4 would win. And so it has come to pass, exactly as
predicted back at the start.

Actually, I think the optimal use of time/energy would indicate a wait of
another year or two before starting the effort to turn off the ventilator.  My
current sense is that trying before then would just result in a lot of
head-butting, with little positive result. Too many people think Asia is going
to rescue it; it needs another year or so for that to pan through.

Someone else got there first with this point (in March '00, to be exact):

Yes, exactly. Which is why some people have bailed on the IETF. Trying to
reform something that complex, and with that many vested economic interests,
by "rough consensus" is just not a workable proposition.
