I would give a try to an OpenBSD 3.3 recent snapshot.

They merged altq in with their pf and transparent bridging code.  So
you can do packet filtering and bandwidth mgmt all together.

Then, combine with ipfm for bandwidth metering and you are set.
(install pftop from ports as well and you can view the current
stateful connections in realtime a la top).

On my ancient Cyrix 333Mhz, it used virtually no CPU on a T1 link.
