3) We're working on a native IPv6 feed to all of our nodes, and would hope to have this live and active before the end of this year. Anycast creates an additional challenge for us in deploying IPv6.
That would be a great thing to see happening. a TLD like .org will quite possibly also be in the position to request IPv6 glue into the rootzone. When this is enabled don't forget to cc the relevant IPv6 lists and ofcourse present your findings to everyone.
There are about 50 TLDs that have IPv6 enabled nameservers now and about 10% of those have already requested changes to the root zone to add v6 glue. One of the reasons for the delay is that ICANN is waiting on the IETF to take action on the respsize draft that is in the dnsops WG queue. --bill
