I'm also interested in shaping NAT. Would you mind telling us what you have in 
mind with your userspace code? Do you plan something like

tun -> your userspace code -> tun
             ^
             | (netlink)
             v
          conntrack

Conntrack is already a perfomance hog - so using user space in that
manner is sinful. The idea is to use contrack netlink to setup tc
rules with ifb. 
In any case, if you are interested talk to me privately;
i have received a few emails since i posted but mostly for people who
want to test.  If you are in that category please just keep pinging me
and i will feel guilty and get it done.

cheers,
