We released an OpenID provider available via IPv6) a month or two ago to support our new social software bug marketplace (also available via IPv6). When we started planning, there were no OpenID providers that were both fully localized in both English and Chinese and let users without OpenID be automatically redirected to a given site after registration. While the OpenID provider has been getting a larger than expected amount of IPv6 traffic (from China's various educational/research networks), we have very little real world experience testing login to IPv6 enabled websites. To make matters more complicated, our ISP (China Unicom) in our China R&D office has been stalling on our request to enable native IPv6 on our fiber line, so we have been limited to testing via tunnels to places really far away. Anyways, it would be great if anyone interested that happens to have IPv6 + OpenID sites would try logging in and let me know if there are any problems.
