Just some random thoughts.

Recaptcha uses a distributed system. Is there any system that solves recaptcha using a distributed system as well?

Maybe such that when the user is prompted with an unknown image and enters it, it gets a point in the recaptcha-solver database.

I understand that this is a large database at google, but then again, the actual "use" google is employing (solving books) means that the verifications (where two or more humans are presented with the same image) should happen within a short time period. And once a word is "solved" on google, they probably "expire" it and hence can be cleaned from the recaptcha-solver db as well.

I am guessing the issue is that this recaptcha-solver would only see a very small portion of the recaptcha traffic and hence google may solve a word and expire it before the recaptcha solver gets a second crack at it.

I am also guessing that just using OCR techniques for recaptcha is not good since the images are actual rejects that google is trying to solve with humans.
