(a) There is ALTQ support for IPFW2 in FreeBSD.
(b) Once IPFW(2) is untangled from main network code and cleanly isolated
    and module loadable, I have to strong reason to remove it.
(c) Noone in DF land actively maintains ipf.
(d) PF has to synced with OpenBSD 3.6.
(e) The interaction of firewalls and a multi-threaded CPU-bound network
    stack has not been evaluated yet. This is much more involved and
    difficult work than "fine grained locking", which can be done somewhat

Just to throw some actual facts into this discussion. Until someone
wants to contribute code for (a) - (e), I'd like to let this thread die.
