I figure if you can time a basic connection command (or ping) to the remote point from at least 4 locations over a long period of time, you should be able to get a good LLA estimate of it. Here's my rough algorithm:[list=1][*]Warm up your GPS (get complete almanac: 12 minutes)[*]Get within range of the target AP/client[*]Establish a connection, and time how long a round trip is (ping, or attempt a connection and wait for rejection) - call this the GROSS TIME
Now how exactly would you connect to the "(non-moving) war-driver"? Also note that (tri)angulation works quite well with 3 points as the name implies.

In trigonometry and elementary geometry, triangulation is the process of finding a distance to a point by calculating the length of one side of a triangle, given measurements of angles and sides of the triangle formed by that point and two other reference points.
Congratulations you win a free ticket to the movies!
