In the end I used NIST Net (http://snad.ncsl.nist.gov/itg/nistnet/). 
While it was nowhere near as capable at simulating whole networks, 
compared to REAL, it was a very simple way to turn my router (naturally 
a linux host) in to a configurable network link simulator.

NIST Net made it possible for me to choose how much latency, bandwidth, 
lost packets and duplicated packets I had between to Ethernet networks. 
This was tres handy for determining how different software would handle 
different types of network connections. In my case I was able to see how 
a particular network-based thin client would perform when the client was 
a long way from the server (high latency) or when the network connection 
between server and client was small reltively small (such as dial-up or
