The latest server patches are on our web page. I have upgraded it.
http://nfsv4.bullopensource.org/patches/ipv6-server/IPv6_patchset.php

It includes missing parts of code. I have started from a 2.6.21 kernel +

I have send them to Bruce few weeks ago. Bruce did you received the URL 
of new patches ?

We hope the interest of community about IPv6 will grow.
