I primarily run Linux. Getting your basic ipv6 connection is easy, under debian derived versions, you do a apt-get install tspc, on redhat, you do a yum install tspc.
That's it. The tspc tool will run automatically and strive to get you your own ipv6 address and route.
This works on about 90% of the networks I've been connected to.
As the address tspc gives you is fully dynamic, you are still as much a cyberserf as you are with ipv4, with the added disadvantage of the IPv6 protocol not actually being useful for much of anything except bittorrent.
Getting a static IPv6 address, and your own, real ipv6 network allocation to play with, is a little more involved. I use Hurricane Electric tunnels as they have great connectivity, supply a useful set of default scripts and are generally great folk to deal with. In the past I've used both freenet6 and sixxs.
The hard part about getting IPv6 access for your whole network is that usually you want to run it on a box that is up all the time. That's partially what pocobelle is about, but there are a lot of other ways to do that - both dd-wrt and openwrt have ipv6 support, most Mac gear comes with Ipv6, although not enabled. I'm told most windows XP systems do ipv6 out of the box, it just has to be enabled - and windows vista and later, if connected directly to the internet, do teredo to get you ipv6 connectivity, so you don't have to do any extra work to have ipv6 turned on.
There are plenty of howtos on the internet. This isn't intended to be one of them.
