Since it hasn't been mentioned yet, thought I'd point out TelstraClear's rough IPv6 deployment statement at http://www.telstraclear.co.nz/sub-sites/ipv6/index.htm

With all things considered, I think it's relatively good news, and great to see one of the main ISPs coming out with such a statement, linked off their main site (I didn't realise TelstraClear had posted such a page until I saw their homepage).

The three key things that I can see, is that all customers will likely have IPv6 by end of 2012, They are confident that they aren't going to run out of IPv4 addresses in the mean time (no carrier grade NAT hopefully) & lastly, their IPv6 connectivity already works.

Also to note, while the article only mentions Fly Buys, I think the fact that NZ Post has taken the IPv6 plunge is a great sign too.
