PS3 to Run Folding@Home

jizziknight writes: CNN is reporting that the PS3 will use downtime to run Folding@Home. From the article: "Pande said that a network of 10,000 PlayStations would increase speeds by a factor of five, and 100,000 would be 50 times faster than what they can do today." The program will not come pre-installed on the system; users will have to download it. Assuming the PS3 sells well enough to make an impact, will enough PS3 owners download the program and run it often enough to realize these claims of increased speeds?
