VERY interesting idea. I think its a great idea. In the very LEAST it could give some quality programmers there first look into AP triangulation. Something that many companies have already written scripts for such as my company. Though i have no idea about programming... I only wardrive ... what i think they did was make a huge database of ever single ping from an ap and use all the pings and a topographical map ect to triangulate and form a 'curviture coverage area' of each ap and checked them back to each other. I hope that makes sence.
Here is some images/webpages to help you understand what i mean!
