I don't quite understand IPv6

It sure would be cool to have a globally accessible IPv6 address on my main home computer, but the good folks at go6.net (formerly freenet6.net, or something) don't seem to have quite what I need.

My service provider at home, Time Warner/RoadRunner is not so friendly to IPv6 internet connectivity. I set up the proper tunnel and firewalls, and I can ssh over IPv6, but the connection is slow and short lived. I'll learn tomorrow whether a last-minute tweak to the firewall makes any difference...but my guess is that either go6.net or IPv6 in general is not ready for this jelly.
