This was my point... Tedd indicated this stuff was trivial, the fact that you can't write it generically suggest otherwise. And as you admit, the one you broke was a pretty bad stupid one :) Now that's not to say that an expert in the field of visual recognition won't do better... but again I'll say, I think it's naive to think that captcha parsing in the generic is not trivial. IMHO, those sites that offer an audio option, probably provide an easier way to break through. I'm pretty sure audio recognition is simpler than visual recognition due to the smaller set (I imagine anyways) of variables.
