You appear to be suggesting that Captcha has failed in some cases -- 
have you seen that? Whilst I agree it's certainly theoretically (and 
been proven in a lab) possible to defeat the captcha, I've not seen it 
in practice.

This is simply a remotely serviced captcha -- not so very different in 
practice from what we have, albeit a little more sophisticated in the 
captcha level, and offering an audible representation of the captcha. So 
if you need those features, then it's a good service -- I've seen it on 
numerous sites.

Here's the PHP implementation: http://recaptcha.net/plugins/php/

Looks very simple. I may take a look at it in a week or so, if no one 
has expressed a more immediate desire to implement it.
