Sounds like a neat system. I am not sure I would know what to do with one. :)
It does however sound like the methods used for the Cell based systems might apply reasonably to it. The main OS runs on the main CPU, and executes tasks on the other processors by transfering the task to them and retreiving the results later when it is ready.
