RE: one data point regarding native IPv6 support

Keith & John are hitting the crux of the issue here. The entire point of the
automated tunneling technologies was to enable application development and
deployment in the face of lethargic ISPs, that will refuse to move until
they see a set of credible applications running in the wild. None of them
will take the risk that the leap-of-faith requires without serious
competitive threat, and that simply doesn't exist. 

I am in the 'enviable' position where both ISP options available to me are
clueful and actually actively working on IPv6 deployments. That said, I am
still stuck with tunneling because the one option that could get me service
today can't keep their basic access network running (the other
work-from-home neighbors around me struggle with it regularly for IPv4), and
the one I use for service has decided to start their deployment of IPv6 in
larger markets (imagine that). 6to4 continues to serve me well for all but
the bone-headed places that have decided to boycott that prefix.

There is no real problem with 6to4, despite the BS being propagated about
failure rates. The fundamental problem is that those complaining have their
heads firmly stuck in IPv4-think, and are refusing to add a second 6to4
prefix to their service. If they would simply install their own 6to4 router
and be the tunnel endpoint, there would be no 3rd party in the path for
either direction. The technology is simply creating an opportunity. Those
complaining about it are refusing to take advantage of it because that would
be a different operational practice than they do for IPv4.

The herd mentality of kill-what-we-don't-like is not helping with
deployment. In fact the ability to document which ISPs have customers that
are trying to use IPv6 despite the edge lethargy is a very useful thing to
drive deployment through blame-&-shame. Put the 6to4-to-historic effort on
the shelf for at least 5 years. Then it will be time to talk.
