OT: captchas

[Tim reid]

I have a question for the CS majors ;)

Captchas
http://www.captcha.net/
http://en.wikipedia.org/wiki/Captcha

Has anyone ever seen any writing on the idea of caching the different
captcha images, manually decoding them and storing the "meaning" of
the captcha in a database.  Then cross referencing the "meaning" of
the captcha with the image filename.  That way you would have the
ability to have a bot load a page/service protected by a captcha, read
the image filename, and decode the captcha.

Is this a valid idea?
