It makes you wonder if we'll ever hear of anyone turning their bitcoin cluster to this purpose. Perhaps someone unauthorized.

well, btc mining involves sha256(sha256(x)). Not being a hardware person, I don't know if the designs of the asic miners can be re-used to just compute sha256. Maybe, maybe not?

Very specific sha optimizations are put into these circuits, which makes it doubtful that they can be reused for any other kind orf computation involving sha.
