- This should be something neat for the tinkerers to work on. It's a free program (http://www.placelab.org/) that uses the WI-FI hotspots and a laptop or PDA to determine your location. Accuracy is said to be 60-100 feet but it works in buildings and behind walls. Not quite good enough for caching but driving should be pretty good.
