One thing you might want to check is the firewall settings on your remote nodes. It sounds like some communication might be stalled some place and this might be preventing terracota from communicating between your nodes. The demo should have agents basically moving around the grid; however, outside of that there is not much behavior as this is just a demo of using terracotta.
Also, if you might want to look at the repast.distributedBatch plugin (more info see: http://repast.sourceforge.net/docs/RepastParameterSweepsGettingStarted.pdf). This enables distributed batch runs using multiple nodes, which might be useful for the type of simulations you want to do.
