I'm currently using a simple bpf program which matches the packets directly
to a linear table. Does per-ip statistics and apparently could handle
quite a bit more network load. The other extra goodie is that it can sit
on a hub and watch by-flying traffic instead of packets having to go
through the statistics-gathering host.

Using skipto to optimize ipfw tables is too much manual labor, I will wait
for radix tree implementation or something like that :)
