The freebsd dummynet driver is all about latency simulation...

linux has a netem which can do the same thing

Also, there is a commercial (reasonably priced) product called network
nightmare. (http://networknightmare.net/)
Cisco also has an .iso that they'll give to customers that's a NISTnet

with it, you can introduce latency, loss, jitter, etc.
