If I recall correctly, Sony deliberately crippled the PS3 specifically so this would not be possible. Did the AF get special dispensation, or did they find a way around the block?
I don’t know
PS3’s used to allow linux but this is no longer the case with the new Slim models. But when it comes to the DoD, I’m sure Sony was glad to make an exception.
I do think you're right. Maybe the government gave Sony an offer they couldn't refuse . . .It seems that that block could only be a temporary effect in any case; someone is bound to just build a supercomputer directly from the components used the the Playstation, it would seem.
