I had a look at the Hurricane electric ipv6 tunnel broker. Quite easy to set up and use .. for an experienced ipv6 tunnel user that is. In literally minutes I had an IPv6 tunnel with a routed /64 up and running. I use that one for a server at work. Now pictures.idefix.net can also be reached via IP version 6. They also offer /48s for people who want to use more than one /64.
