I was a core member of KAME project. The project had concluded at 2006 March, though, the activity of Mobile IPv6 implementation continues. Now, we are ready to port our Mobile IPv6 stack called SHISA to FreeBSD. Until complete it, use the kame snap if you want to use MIP6 or NEMO.
And, I have a personal project that aims to port SHISA to Darwin/MacOS X. Check the web page https://www.momose.org/macosx/mip6.html
