While I agree with both X and Zen, I understand where you are comming from. Cliff's book generated the same feelings in me when I read it the first time years ago. It is an excellent read, and it does make you sit back and "what if..."and "wouldn't it be nice if...." I guess thought provoking is the best way to describe it.

Another book, thou completely fictional, that is starts making you think about peoples motivations and security is Bad Memory by Duane Franklet. While not even remotely the same as Cliff Stoll's book... it WILL make you sit back and go "Hmmmmmmm......"
