The standard method for getting around CAPTCHA pages is to either
  1. hire cheap labor
  2. create a very popular page of your own - usually pron
    1. copy the CAPTCHA image to your page
    2. get the input from someone who happens by your page
    3. send that input to the original page
Otherwise, you'd need to create some seriously smart image processing. Perl would be a great choice for that; once you have some code and get stuck, post it here and we'll be happy to help.
