Wow, yet another insightful comment! many thanks. The two-man rule is a good idea - not fool-proof, but I suppose nothing really is. And the story about the heavy device on nuclear subs; that's brilliant!

It really seems like ease of access is the enemy; that's a pretty fruitful take away. I do hope you share your blog post about the Gozer Principal on HN when you're done, I look forward to reading that.
