I had suggested something similar on kclug chat a while back. specifically, software that could be used in conjunction with each other with three laptops using signal strenght for triangulation. It would require three mobile units in line with each other or parallel with each other running and using some type of free map, Google maps perhaps? i think it is possible to nail wireless transmitters down to the room in a house this way. High rise apartments could be done the same way by two on one floor, and a third under provided the halls ran the same way. the same could be done for locating wireless laptops in any public building.
