what's interesting is the chicken/egg problem of
users/content/ipv6.
What's driving v6 deployment?

Currently, it is IPv4 exhaustion. As for content, that can
be tied to
users in some situations, for instance VPNs. That's why I
think that a
lot of the worry is premature. Instead of figuring out how
to deploy
IPv6 to grandma we should be thinking of which early-adopter
communities
could use IPv6 services and help us, the network operators,
climb up the
IPv6 learning curve so that we will be ready when IPv4
shortages start
to cause pain to us and the average customer. Before we run
out of IPv4
addresses, some of you will be explaining to Joe Sixpack why
he cannot
get his DSL line moved to the new house that he just bought
because it
is served by a PoP that has run out of v4 addresses. Or you
will be
explaining the additional $30/month v4 addressing surcharge
that he will
have to pay if he doesn't take the v6 option at the new
house.

Today we only have to solve today's problems in order to
learn what we
need to do to solve tomorrows problems. We may learn that
tomorrows
problems are a lot easier to solve than we thought.

Perhaps it was this one?

Note that Level3 did choose to use 6PE for their deployment
rather than
dual-stacking.
