Why multiple instances? Multiple threads, async. I/O, or other approaches should provide the same benefits separate instances would (e.g. better utilization of system network and disk resources) while being much easier to implement.

I'm not sure how efficient current implementations are in this regard, but if you want to really test the core BT algorithms instead of just current implementations, you may have to add these features yourself (or persuade someone else to do it :P).
