Great idea. And not a bad one that would be applicable to CAPTCHAS as a whole. If non-technical. E.g. ask the user like 'What color is a US Dollar Bill'
I've lived in the US, and I had to look at the dollar bills I happen to have in my wallet. Green, yes, but did they add other colors recently? Not a very foreigner-friendly question.
The problem with technical questions, is that no matter how simple, people here will argue about the correct answer ;-). Unless we just give up and say that "It depends" is always correct.
