Here's a "get-rich-quick" idea. Set up a website that allows a user to enter his/her location and it automatically pops up a list of possible threats, local wild edible/useful plants, weather patterns and temperatures, etc... Then allow the user to buy a bound, pocket-sized book containing that information along with normal survival skill information.

Anyone have the know-how/resouces to build such a thing? For the right price I'm willing to be your traveling researcher to find out the information.
