We could encourage Hyperion to support OS4 on IBM's bleeding edge Power series of systems, but the cheapest models start at $5500. Not exactly cost-effective for hobbyists.
Or, we could live with the mediocre performance of the Cell/BE PPU, port OS4 to the PS3, and be done with it. PS3s aren't exactly rare or at risk of going out of production any time soon. ;-)
