I should emphasise I'm a sysadmin rather than a service provider, and 
I'm mostly speaking generically based on conversations with a number of 
I've been trying to get my service provider to sort out IPv6 for a while 
now (they tell me their infrastructure is ready, but they're being lazy 
about getting blocks sorted out) and already done as much preparation as 
I can with my infrastructure to ensure its ready for it.
That said there are no services we use that are IPv6 only, nor are there 
likely to be for a while that I can tell as none of our service partners 
are talking about it, and nor are we getting reports of anyone unable to 
access our services due to lack of IPv6 on the front end.

I know how ugly that sounds, I really do, but that's the way most people 
will see it.  You have to provide incentive to make a change, and "It's 
better" rarely is enough.  "People won't be able to access our site" 
sure helps but being unable to put a date on it still reduces incentive 
(especially when Management get involved, and especially if there is a 
financial outlay involving firewalls etc.).  People bury their heads in 
the sand and will continue to pretend there is nothing wrong until 
they're /forced/ to change.  As much as it was a hideous and inaccurate 
article, that Fox news story that was posted on list the other day came 
up was great for fighting for change.  The grossly inaccurate 
end-of-the-world text provides a good hook for getting the lumbering 
beast moving in the right direction.

The White House's push for IPv6 amongst federal agencies is currently my 
best guess at what will probably see the first thing to transition to it 
from my perspective at work, though I sincerely hope we'll be on IPv6 
long before that happens.  As for when we'll switch internally?  No 
idea.. all machines have IPv6 so some local traffic probably uses it, 
but most are still based on IPv4 and until I have time / money to make 
some other infrastructure changes will remain that way (our office 
environment equipment can't handle IPv6, unlike our production environment)

I'm sure there are some cases with IPv6, yourself as an example, and I 
know an ISP I worked for in the UK had a customer several years ago who 
had a critical need for it, but that's still in the minority.  In every 
case as soon as there is a business reason for it and its compelling 
enough people will take the time to make the transition.
