These might be of interest:

UrbanSim

Deep Green

I have been thinking about doing something very similar to the UrbanSim concept, but as a commercial product, and reflecting my own particular view of network defeat.

With regard to the Deep Green concept, anyone interested in it might also be interested in the subject of genetic algorithms (also, see the Robby the Robot examples on the net, such as this one. Read about GAs recently in Complexity: A Guided Tour).
