Hi Spidey, If you want to go low-cost (free), try http://ipband.sourceforge.net. It won't let you limit connections that are hogging your bandwidth, but at least you know who the hogs are. If you want full bells and whistles, http://www.packeteer.com/prod-sol/products/packetshaper.cfm. This one will let you do anything you want. Exprensive but worth it. Hope the info helps.
