Well, I'm not quite sure how you would go about that. I suppose it would depend on exactly how the internet is distributed after the satellite ISP gets it to you. But one suggestion, if those "yahoos" are tying up that much bandwidth, that means they are probably doing something that takes and extreme amount of it to begin with like games or downloading music/movies/etc. What I would do, is set up a firewall to block all that traffic. Only allow connections to go out if they are destined for ports 80, 443, 25, 110, or 995. This would only allow people to use the internet connection for just web browsing or sending/receiving email. No more games or obnoxious downloads that munches up all the bandwidth.
