And what what if the stock is magnetic? ("Where's the fridge magnet isle?") ... and doesn't the earths magnetic fields change also? There's a number of questions I'd have about the stability of the data being collected and how quickly it'd go stale.

Every phone using the app can contribute to your map data. If you combine magnetic data plus wifi data plus user behavior data, I expect you'd be able to continue to provide good 3D data to users. I'd bet the hard part is getting building owners to update things regularly. Who's going to remember to change the map when the grocery store moves the cereal from aisle 2 to aisle 7?

  Maybe the maps could auto update using a combination of >magnetic data plus wifi data plus user behavior data

  You raise another point I haven't thought of: 3D. People are different heights... surely that changes the fields too. Interesting problems to be overcome.
