not really. but apart from the plumbing into the interfaces,
this is just the FreeBSD/head ipfw code with obvious features
disabled (e.g. there is no access to local sockets or address
lists or routing tables so things like 'me', 'uid xx', 'verrpath'
do not work).

And it could definitely be improved to work on more interfaces,
become multithreaded etc, but this is an exercise that i hope
someone else will take over.

cheers
