Yes, there are lots of folks with IPv6 connectivity and v4-only recursive DNS servers. I don't think ISPs will have problems setting aside a handful of IPv4 addresses for authoritative DNS infrastructure to work around this until v6 transport in recursive DNS servers is common enough.
Dave,I think part of the point of this is to discover gotchas with our current infrastructure. For example, while diagnosing why I couldn't get onlyv6.com to resolve on one of my name servers but the others worked fine, I discovered that PowerDNS Recursor won't use an IPv6 address for outgoing queries unless you actually give it:
query-local-address6=One of my name servers had it, the other didn't, hence I was getting failures on one and success on the other. Its little config issues like that that can crop up weeks/months/years later and make life difficult.
Now that I'm a Xen shop, I design domUs to last years at a time rather then rebuilding them constantly. Being able to shunt stable and reliable domU hosts to new dom0 machines when they come up is a great thing, and makes my life alot easier. :)
