Greetings all,
	We're putting together a firewall for the primary purpose of ensuring fairness for a user base of around 600 students. We're looking at a copy of different models for controlling bandwidth. We will have an 3 megabit connection to our provider.
	We were looking at limiting connections to 128kbps, so each user could download data at about a megabyte a minute. The only problem with this is that it prevents students from using the full bandwidth potential when it might otherwise be unobtrusively available. Are there any good methods for permitting connections to use all available bandwidth unless other requests are made--and then fairly divide the available bandwidth so that it is equally (as much as possible) responsive for each user?

And finally a last question... Were we to setup limits on transfers--like 2gigs in a week per IP address, does anybody know of any good FAQ's or guides of how to do this well?

Thanks for your time,
John Tracy
