A much much much easier way is to use a PC, load the dummynet image on a floppy disk, then in about 5 minutes with the right configuration, you have a simulated WAN, including bandwidth and delay.
Dummynet works on FreeBSD or, as we do, you can download the version that fits on a floppy and boot from it. We use it to teach our application developers the hard lesson that not everyone has 100Mbps link to the servers, most sites have 64kbps.

I was hoping to set up a demonstration on the impact of high bandwidth*delay product networks without actually having a high bandwidth*delay product network. By artifically enforcing a small rcv window, I should get about the same result.
