I can say that we (NTT) have been IPv6 enabled or ready at all customer ports since ~2003.  Anyone else who has not gotten there in the intervening years may have problems supporting you for your IPv4 as well :)

You should be able to get native IPv6 in Seattle from a variety of providers.  If you're not finding it, you're not really looking (IMHO).

The tunneled part of the "IPv6" internet fell to the wayside a long time ago, there are stragglers and I have even seen people try to peer over tunnels in 2010, but anyone still adding that level of overlay (v6-over-v4) may find themselves in a world of hurt soon enough.
