We did some interoperability testing between the UCLA code and the Microsoft code, but we never picked up the code, and in fact had toruble putting the UCLA software together until Yixin somehow put a kernel together that would work for our test. It was a proof of concept, but it didn't go beyond that. The UCLA code was built on the Francis' stack from Inria, and I don't know how different that is from the KAME stack. Francis had the 6over4 from UCLA in his code when we went to Tokyo last year for the interim IPng meeting and TAHI interoperability test - I helped him do a little interoperability test there with Richard Draves from Microsoft, by giving them a multi-hop IPv4 network with multicast service - it was no surprise to any of us that it worked, but it was nice to see. So, Francis - you are the last person seen (by me) with a working 6over4 on freeBSD!
