right, i've used that, but that uses bpf. because it has to.
it also asserts its own ethernet address, so if the kernel didn't
rewrite the source ethernet address when transmitting the packet
(never mind deciding which interface on which to transmit it), and
then rewrite it *back* when replies were received, it wouldn't help
i don't think that's it.
