Simulating bad network conditions

[xorquewasp at googlemail.com]

Hello.

I want to verify that a program I'm developing works correctly
in poor network conditions (high latency, random packet loss, etc).

I seem to remember reading something once about somebody simulating
these conditions with PF but can't remember where.

Anybody got any ideas about how I could go about doing this?

Ideally it won't involve starting up a hundred large BitTorrent
downloads and randomly ripping out network cables...

thanks,
