if you read the ARIN statement on IPv6, you will find that Keith
is describing the story of how to cook a frog. soon, (pick your
favorite study) all IPv4 space will be allocated. For folks who
need IP access after that time, IPv6 will be available. Its those
(ones and twos) who will need to access you email and web sites over
IPv6 (or via the IETF depricated NAT-PT or other ALG)... It won't be
a massive sea-change, it will be a gradual shift. Those not prepared
will see a gradual leveling off of traffic/load - as the IPv6 only clients
find other places to go to get the services, capabilities, and features
that they desire.
so in general, I think that Thos might be on to something.

I think that's a pretty bizarre way to measure IPv6 deployment. The
_last_ applications to support IPv6 will be the widely popular apps that
depend on an extensive infrastructure of servers that are currently
associated with IPv4. Email and the web both fall into this category.
And as long as a site (practically speaking) has to support SMTP over
IPv4 in order to accept incoming mail, and HTTP over IPv4 in order to
make its web pages readable to most viewers, there's little incentive
for that site to advertise an AAAA record for either server.

The article is by Thomas Kuehne and is a "quick-and-dirty" study he did
of how many web sites were configured with AAAA records. Obviously
it's not a comprehensive study, but just another data point about the
readiness for IPv6 - or not. I've included the intro to the data below.
