"no base stations currently provided IPv6 functionality"
If this is true, it's more than a bit of a worry - the first place that IPv4 addresses will run out and where operators will need to offer IPv6 addresses is the mobile space. After all, most of the smartphone handsets are already IPv6-capable.
By the time local ISPs start to really hurt for IPv4 address space (mid- to late-2012 maybe in parts of the APNIC area?), the vast majority of the fast-churn smartphones will be IPv6, but very few home fixed users will be. For example, in the NZ market, you CANNOT buy an IPv6-capable ADSL modem from a mass market supplier even today, and these boxes last far longer than the 18 months to three years of a typical smartphone.
So the first part of the market that needs to go IPv6 is the mobile part. And there are *no* base stations that do IPv6?
