I also think so, but that is not in my competence. But I, after two days
of discussion, I must say another thing:
WHERE ARE TESTERS ?!
You all are wanting this node to be included into FreeBSD src tree, so
that it will be available in standard distribution. But before this code
should be tested and bugs fixed, if any. And I don't yet see any success
stories / bug reports !

Good idea, but still to be worked for more P2P types examples, and BPF
assembly language explanation, as I suspect some things can't be done but
tcpdump expressions, though still possible on ng_bpf. Unfortunatelly I do
not have much time for this.
