Broadening the IPv6 discussion

Since we're on the topic of IPv6, I wanted to gauge the current attitude of the ops. community toward its deployment. We're seeing a lot more interest from our enterprise clients in using v6, especially as things like VoIP and PDAs consume their address pools, and NAT gets in the way of collaborative apps such as netmeeting and business-to-business connectivity. However, the road-block seems to be the lack of ISPs that offer IPv6 services. Given that places like China & Japan are now mandating IPv6 for their ISPs, does anyone see anything resembling a growing momentum toward IPv6 adoption, or is it still a moot issue for you guys? Irwin
