this sounds like a slight exaggeration, but I do think that the main 
incentive to deploy v6 will come from the need to communicate with global 
addresses to points *outside* of folks' internal networks.

it doesn't follow that deploying IPv6 internally to a site does no good
at all - it will of course do some good if the site has applications
on internal hosts that need to communicate with external hosts using 
global addresses.  and of course having v6 deployed internally would 
allow the site to run those same applications interally without any 
configuration changes.

but if you're trying to make the point that there's little purpose in
having your own IPv6 island - I think that's basically right.
