How to allocate bandwidth on a router?

[Xenon14]

My friend is rooming with 3 other guys, and they bought a 1.5mbit DSL line. Unfortunately, his roommates insist on downloading movies from dusk till dawn, and most his online performance is cut to 56k baud speeds. They're using a Lynksys BEFSR41 ver 2 router. How would he go about splitting up the bandwidth evenly, so that each person is guaranteed a certain amount of speed.

#1, netowrking would be a better place for this.
#2, there is a program in XP to do this, but it is porly documented.
#3 use one of the many firewall software routers out there. But you will need an extra box.
