This presumes that there is content or 'reason' (which I short circuited
to 'content' for this discussion) available on the 'v6-internet', or
atleast accessible to a v6-only client. Other wise having a connection to
a network with nothing and nobody of consequence to that customer isn't
going to fly.

but ipv6 is more secure, yes? :) (no it is not)

i agree, though we are back to the chicken/egg scenario with
users/content yes? without users of significance google isn't going to
expend capex/opex to add ipv6 (i do use google in the example purely as an
example, vint might have them busily working on interplanetary IP and ipv6
for all anyone knows) The same goes for every other content place. I'd
venture to guess that even enterprises aren't rushing to ipv6 for very
similar reasons, there are no things their users need/require on an ipv6
only stub, they have other more pressing concerns (virus updates for

i'm not disagreeing or saying that ipv6 won't ever get deployed (or even
in time for ipv4 exhaustion) but... chicken/egg, sometime soon folks are
going to have to take it out of hide to start down the v6 path, some one
is going to have to convince their upper management that they really do
need to put this 'new service' that 'no one is asking for' and is 'still
somewhat experimental' (from a hardware/software/OSS perspective atleast)
onto their production infrastructure that is supporting YMillions of $$.
