i would like a program that could limit how much bandwith each program is allowed to use. is there such a thing for the mac?

what netlimiter does (from the website):
NetLimiter is an ultimate internet traffic control and monitoring tool designed for Win98/Win98 SE, WinME, Win2000, Win2003 and WinXP. You can use NetLimiter to set download/upload transfer rate limits for applications or even single connection and monitor their internet traffic.

I have seen some other apps that do this for OS X, but I cant seem to find them at the moment.
