Considering the way that I've heard some people talk (firsthand and strangers no less! lol), you'd probably make a killing on such an idea, Jammer. No pun intended. It's kind of like the underground shelters that I saw that were selling like hotcakes apparently. Expensive things, too. Even if the purchasers didn't always acquire them because of some feeling of approaching apocalypse, it still signifies a pretty dismal worldview that they feel like that they have to stick more than just their heads in the sand, lol.

In every man there is something wherein I may learn of him, and in that I am his pupil.--Ralph Waldo Emerson
