As long as you mean the multiprocessing module, that's correct. Alternatively, you can use the reactor's spawnProcess method for creating processes, or Ampoule if you want a process pool (which is nice because it works remote, too). Perspective Broker and it's object-capability successor, Foolscap, are more full-blown distributed computing tools, but they would work fine for this as well if distributed requests is what you want :)

Of course, all of this mumbo jumbo is probably only required if you can't manage to saturate that network link with a single core :)
