You can do it with the ipv6tunnel.o included in the MIPL Mobile IPv6
code (which is exactly what you thought, I suppose).  There is a
utility called ipv6tunnel which is used to set up tunnels manually
from userspace.  To use this enable CONFIG_IPV6_IPV6_TUNNEL in your
kernel.

I don't know if the USAGI team will use our code to implement the
generic tunnel device, but everything should be working with that as
far as 6over6 is conserned.

Should be no problem.  We have a 6over4 tunnel to 6bone and I run
6over6 on that.  Very similar to your setup I guess, though in my case
the 6over4 and 6over6 end-points are different nodes.
