I'm not motivated enough myself to do this, but if you like tedium (and it is important enough) you can always screen capture and OCR using a Kindle or Kindle4PC/Mac. Probably could automate this to some extent fairly easily also.

I did a small experiment with Kindle screen captures and Acrobat's OCR, which proved very accurate in terms of capturing the raw text. Alternatives would potentially do a better job preserving text attributes and formatting.
