Probably possible (and I still think you'd be better off with those libraries, which are, after all, just access the packet filter sockets), but don't know if it is worth it. Why not use User-Mode Linux (http://user-mode-linux.sourceforge.net)? You get the whole kernel, including the networking stack, running in user-space. You can run several virtual machines on one real host, and get to network between them in a couple of different ways. Might even be worth doing if you had your own user-space implementation of the stack, as the environment in which you run your implementation.
