I setup yesterday IPv6 via 6to4 with tunnel from Hurricane Electric.
It just works. I still have to do some tweaks like as I am using a dynamic IP, the tunnel will go down when my IP changes. I also need to do a couple of other minor things. It was interesting to see that my local squid running on IPv4 was actually forcing my browser to go out via IPv4... oops.
But I like it and I will do more with it. My aim is to focus primarily on IPv6 at home, ie. that clients only connect by IPv6 - when they can. I am sure, that my network printer doesnt know anything about IPv6.
Ok. Next stop DNSSEC.
