Is it working for you behind a router? Last I tried it (when they first flipped the switch out West) it was only working for a single device. Or rather, IIRC, it would only route for each device that asked their server directly for an IP. Which ruled out getting a /64 and having machines configure themselves with a simple radvd setup. The router would need to proxy all that configuration traffic :P
So I went back to my tunnel and haven't heard a whisper that anything had changed. I'd like to skip the tunnel if they've now got that working.
