So let's just go easy on the guy! It's not an entirely unreasonable request, and not really up to us to judge it. It may well be legit!
Depending on the quality of the CAPTCHA it may in fact be possible. But you'd probably have to wrap in an OCR library with some image processing (to TIFF) beforehand. For image processing I'd recommend rmagick[1]. For OCR you could look at gocr[2], ocrad[3] or tesseract[4] [1] http://rmagick.rubyforge.org/ [2] http://jocr.sourceforge.net/ [3] http://www.gnu.org/software/ocrad/ [4] http://code.google.com/p/tesseract-ocr/ Good luck with that!
