We really need large commercial transit players like Global Gateway, TelstraClear, AT&T, UUNet, AsiaNetCom, and Sprint to start offering dual stack IPv6 connections to downstream ISPs, and for ISPs to start allowing clients to connection via IPv6, including via DSL.
Here is an interesting presentation by Robert Rockell of Sprint about IPv6: http://www.nanog.org/mtg-0405/pdf/rockell.pdf . Slides 5, 7, 9, and 10 are very valid as to why this is unlikely for a few more years to come. The major driver will be customer demand (read: $$$$), or the network operators themselves finding resource shortages are impacting on their operations, thus moving to a v4-over-v6 core. That said, Sprint do offer semi-native v6 transit, and I believe UUNET also.
We really need to get critical infrastructure, like DNS, fully IPv6 enabled. The .nz domain isn't even reachable via IPv6 addresses yet. Now I know the shared registry system has IPv6 support now, but it is limiting in that you must still supply IPv4 addresses. You can't supply only IPv6 glue records. What happens when you can't get IPv4 addresses to use for glue?
This is a very valid point though, and should be raised through the SRS/INZ I guess. aj. -- (atm and ipv4 for ever. yeah.)
