I haven't done it, but something like a squid server on your gateway machine
with authentication requirements. I think it can be set up to change based on
the time of day (maybe using a cron job or similar). Of course, you will want
to set up junkbuster or similar on this machine as well.

Squid also may save you some of your MB usage in any case, so your brother
can do more surfing for the same MB limit (then again, maybe not).
