(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
mechanical.
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.
