filtering users by mac address and limiting bandwidth to each mac.

I was wondering if there is a any way to filter users on a network by
mac address and if i could allocate a limited ammount of bandwidth to
each user in chuncks of 768 - 1.5 mbps with their macs using linux? I
am working for a wireless isp for a school project. some of our users
are only paying for 768k of bandwidth and getting the whole pipe. so
this box would a dhcp server, mac filter, and bandwith limiter. is that
possible?

Yes, you can filter the users with iptables -m mac --mac-source and
you can adjust the bandwith using iproute2 and the 'tc' command. You
can read the lartc document at lartc.org that explains how to adjust
the bandwidth.
