Have you seen:

  http://wanem.sourceforge.net/

It's basically a bootable CD that can be used to emulate a
wan. Various packet loss, rtt settings can be simulated. Basically
boot and run. I have used iut for testing performance of a web
application over lossy networks. It works well for me and means I can
use any random box I have easily since I can return to normal state
just by booting the box without the live cd in the drive.
