I'm doing some stress testing on a web application I'm making. I wonder if there's any software out there that can make my LAN network slow down to 56K modem speed. Or perhaps someone got suggestions on how I can find out how my app will function in a slow-band environment.

I can't use the services on the web, because the client has to use a fingerprint-pad. (I'm working on a fingerprint log-in solution).

Any help will do!
