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

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.
