Hm, I'd like to see some stats on that, particularly regarding his
various prognostications about IPv6 :-)

You've just described why tunnels are great solution right now, even if
they may not be in the future. Right now, they let you get up and
running with IPv6 quickly, while traffic levels are low and the payoff
Even if you were right, which I obviously don't think you are, then why
is using tunnels just "to play with and get familiar" such a bad thing?
That's exactly what people should be doing if they can't get native IPv6
- getting tunnels and getting into IPv6 whatever way they can.
As to them being a "hopeless joke", perhaps you could explain why you
think that to be the case? Geoff's argument didn't hold water, I wonder

Interesting, but completely irrelevant to the question of whether or not
tunnels are a useful tool.
