I imagine a plugin that modifies the login screen to use <http://recaptcha.net/>. You would then be required to fill in the captcha as well as log in in the normal way.

Okie - I have a first pass of this. There are still some issues.
Currently the code verifies the CAPTCHA. If you get it right then you're fine.

Instructions
=====
You need to go to <http://recaptcha.net/api/getkey> and get a key set.
The keys are added as options.
- reCaptchaPubKey => "LONGPUBLICKEYSTRING",
- reCaptchaPrivKey => "LONGPRIVATEKEYSTRING",
+[[!format perl """
+reCaptchaPubKey => "LONGPUBLICKEYSTRING",
+reCaptchaPrivKey => "LONGPRIVATEKEYSTRING",
+"""]]
You can also use "signInSSL" if you're using ssl for your login screen.
