Ok, I'll try to enlighten you a bit here. I already had many similar  
questions and it seems that it is not very clear in people's mind.  
People from USAGI will correct me if I'm wrong, but knowing a bit  
about each project, I can tell that:

USAGI and KAME are projects within the WIDE organization (http:// 
www.wide.ad.jp/):
- USAGI works on IPv6 and IPsec stacks for Linux,
- KAME (that was stopped in March 2006) works on IPv6 and IPsec  
stacks on BSD variants. They also develop a MIPv6 stack for BSD  
(named SHISA), but this has no relation with MIPL2 not UMIP.

USAGI and Go-Core joint their effort to develop MIPL2 until summer  
2006. MIPL2.0.2 that runs on a 2.6.16 kernel is the latest release  
from that joint effort. In order to maintain MIPL2 to the latest  
kernel Linux kernel developments, USAGI maintains and releases UMIP,  
which is in fact MIPL2 + a set of patches to maintain MIPL2 to the  
latest kernels.

Is it more clear for you now?

Be careful, kernels 2.6.21.5 and 2.6.21-rc5 are not the same.

BTW, note that USAGI provides a howto with useful information here:
