still use the Stochastic Fair Queuing packet scheduler under Linux, if I
had to make a choice. IIRC, that supports the DiffServ marking as a
filter for which bucket it throws packets in, at least through the
tc_index mark on packets.

SFQ also has a good rap from people who know the IP stack very well and
is reported to be less CPU intensive than others without penalizing
interactive vs bulk sessions.

*nod* For a community network, I expect to see different QOS between
different links, with the majority doing nothing but bridging or routing
packets FIFO. :)
