That description sounds like it simplifies to "limit bandwidth based on
IP address" - which is fairly trivial for ipfw+dummynet or pf+altq.
ipfw+dummynet is really ugly traffic "shaper" (let's face it there is no
shaping going on), because instead of limiting bandwidth it will drop
packets to simulate bad connection. I hear many years about "trivial"
configuration per user bandwidth limit with pf+altq but never saw ANY
code... You can't set bandwidth limit with PF like 3Mbit per 100 clients
if your lan card is 100Mbit. This is just lame- in reality clients never
use all bandwidth and never all clients are connected all the time. Even
Linux ipfilter does it for years with insane cryptic commandline but it
just works.
ipfw+dummynet can also filter on uid/gid but I believe there are some
race conditions in that code
