Thanks for the reply dmorris.
I've been following the IPV6 stuff kind of lackadaisically for awhile, but in the past few months I've been starting to see that it's going to be a Really Big Deal within the next few years. The current predictions are that we'll be functionally out of IPv4 addresses sometime in
2010! It may take longer, or it may happen sooner, but with that date three years away, I guess to sooner people have real IPv6 solutions available, the more marketable their products will be in both the short and long run.
