The best interview question I've ever had or thought about was also of this style: one concise question that requires knowledge of many different domains, and spawns a conversation that lasts the whole interview. The interviewer also pursued the same strategy of pulling actual numbers (for storage requirements) out of me. It was a tremendously enjoyable and satisfying interview (as far as interviews go). Also given by a well-known search company, interestingly enough. I didn't give nearly as much pushback as the author, though, since I assumed that wasn't the point.
