Why not run an IP over IP tunnel b/t 2 boxes using the tun device
and put sleep()'s in the userland program that implements the tunnel.

Someone just posted some code that implements an IP over IP tunnel,
and it shouldn't be too hard to make it throttle or just induce
delay.  Yay!  The fearsome tunnel 'o lag.

Or you could try underclocking your ethernet cards...
(I've heard of some people in the linux camp that have done this...)

Have a good one.
