Back in the lab at school we had these two huge ancient boxes which were
cable of doing this. They could simulate anything from a clean 10 foot
loop, to an extremely noisy satelite link.

You may have to do some hunting to find used equipment like this..

For serialization delay, reduce the speed or increase the packet size,
or both.
For propagation delay, order a satellite circuit or several hundred miles
of wire, or move one end of the circuit to Australia.
