I really, really want to be able to search for what products are available on the high-street in any shop, based on a live stock-room database.
Imagine an application which could recommend what exactly you should do in order to obtain item X based on your location, the amount of time you had and how much money you wanted to spend.
E.g., "I'm at home and I need to pick up a pair of smart shoes. I have an hour, and £50 to spend. Where do I go?" - the application has two nearby places. Place A has smart shoes for £35, and it'll take you 30 minutes to get there, but place B Is only 10 minutes away but you'll have to spend £45 on the shoes. Trivial example, but that sounds pretty useful, no?
If anybody has a solution for this and wants to talk seriously about implementing it, get in touch with me.
