aaron -- 

i think the best feedback would from the implementors who participated 
the impact of user testing upon their approach to the problem:

Ben Maurer -- reCAPTCHA point-person (Carnigie Mellon University)
Colin McMillen -- reCAPTCHA engineer
Chris Blouch -- AOL implementor
Don Evans - AOL 

Joshue O Connor (CFIT) -- provided user testing footage and feedback

and i'd talk to norman walsh, as his solution to the bot versus person
question is based on simple computations, rather than pictures (yes, 
there are definite problems with "what comprises a 'simple' computation?:
what if implementors substituted pictures of numbers and operands to 
provide a false sense of double-security)

as for an executive summary one really must follow the threads on 
wai-xtech to gain a complete picture of the CAPTCHA and reCAPTCHA
discussions and implementations, but here are the "highlights"

gregory.

the initial major problems outlined with reCAPTCHA and 
reCAPTCHA's approach to rectify them are both in a single post:
