Understood.  Ask a "complex" problem spelled out in a sentence that even
if a bot could parse, it still could not "understand" and answer (that
is, until "the singularity" :) ).

Localizing this could be hard, as the world doesn't necessarily speak
english.  It would need to be some sort of elementary mathematical
problem, requiring a typed answer.

Hmmm... I haven't been focusing on this, but it is worth a read.  I am
working on making the pages as simple as possible (no AJAXian-ness) for
a combination of aesthetic and personal time reasons.  Any pointers to
document design elements to encourage accessibility you can provide
would be appreciated.

Now thats a really interesting captcha ...  using audio ...  wouldn't
work for deaf readers though.  But your point is well taken.  Don't make
it harder than it needs to be.  Make the test more useful by segregating
machinations of the test, from the cognitive process and response.
Since blind and deaf users, and pretty much all users, have the
capability to enter keyboard (or keyboard like) response, and all should
be able to "read" text from the test, keep it simple, and text based.

Thanks, will think about this.  Have some ideas already.
