Preposterously Parallel iPods

Here's a question: How many FLOPs in an iPod?

Climatologists, up the road here at LBL, claim that a supercomputer using about 20 million embedded microprocessors, such as those found in cellphones, iPods, and other consumer electronic devices, would deliver useful climate simulation results at a cost of $75 million to construct. A comparable supercomputer could cost closer to $1 billion. Based on a recent post, I'd be wanting to see the front-end compiler system that can upload 20 million processors.
