	Now you lost me. What you're saying is that traffic is purely
symmetric between any two hosts? I don't think so. But the truth is,
you can't do much useful stuff at the input queue of a shared-memory
router such as a PC, because you shouldn't have much backlog there. (The
memory is not the bottleneck, the network interface is.) Or if you do,
your PC is always working in interrupt mode, and that shouldn't be.
