Aw good question, Inu... I have no experience in running multiple sims on a standalone configuration. In my limited knowledge, "standalone" meant "single sim on my computer".

I think that there is no way to run multiple instances in standalone mode, since to the best of my knowledge, all communication between instances happens through grid services, but I might be wrong.
