a clue to Microsoft? Some of us are already on the IPv6 backbone via a tunnel set up with a Linksys router.
Although I occasionally have to log in to my tunnel broker and reset the tunnel (due to my ISP changing my external IP), I don't have to make any configuration changes to my laptop. It auto-configures thanks to the radvd daemon. Just boot and go.
It should be noted that the firmware that I use on the Linksys is almost a year old. The newer versions include QoS and better network management tools.
