Seeing that we now have Geekzone IPV6, I thought it would be good to post here how to get IPv6 connectivity.
The easiest way is to get an IPv6 connection from your ISP. There are very limited alternatives here at the moment, but WorldxChange is running a very limited trial. This will most likely require new modem/routers for connectivity.
Another easy way is using a tunnel, such as Gogo6. Just register and install the software. You will be assigned a dynamic IP address. If you register for their Freenet6 service then you can specific a username/password and be assigned a static IP address - and get to chose which node to connect to Sydney being the closes one would be faster).
There are other options, so feel free to post here.
