pf in FreeBSD is pretty well maintained.

altq currently has no maintainer (at least that I am aware of).  It's
a difficult problem, altq needs to "learn" a lot about multithreading.
I'm not aware of anyone working on it, although Patrick Kelsey
(pkelsey@) may be worth a ping (IIRC he might have looked at this
problem a bit, I'd bet he could do it if he has time and some entity
can sponsor the work).
