if what they need to do is create new endpoints that need global reachability
to existing endpoints, then deploying ipv6 is all cost no benefit.  the cases
where someone only needs limited reachability to themselves and their partners
is generally being handled with IPv4 RFC1918 space today, and while ipv6 makes
that better, the betterness in that case does not relieve any pressure on the
non-RFC1918 ipv4 pool.

there are not enough ipv6-friendly customers, simply because there are not
already enough ipv6-reachable endpoints.  pulling oneself up by one's own
bootstraps may sound wonderful but it doesn't actually work.  in the long
run, incorporating ipv6 into an organization's technology DNA is the rational
choice, but we're not in the long run yet, and there are more costs and
disadvantages than there are benefits and advantages to being a first mover,
unless you're helping create the basic IPv6 technology (as in ISC's case).

it means if i only had ipv6, i could not send you e-mail today.  thanks for
calling me a dns guru, you made my day, even if other employees of ISC have
to clean their keyboards after explosively laughing coffee out their noses.

so, it's a <a href="http://www.youtube.com/watch?v=rSBNT5WKizg">hairball</a>?

i think we all like our customers.  but bt.com could show some solidarity for
the long-term rational choices we'd like folks to make, if you'd make all of
your corporate I.T. resources ipv6-reachable, and make all of your corporate
I.T. desktops ipv6-capable.  that's in addition to the technology DNA infusion
you're describing, so that your company will be well positioned once everybody
else has also added ipv6 to their products and services.
