This is related to, but NOT A DUP of, the post incorrectly titled "Google map a cellphone knowing its MAC address" at <a href="http://news.ycombinator.com/item?id=298073" rel="nofollow">http://news.ycombinator.com/item?id=298073</a>. The article intruiged me but I knew there had to be an easier way to send any MAC address to their API since there is no way for them to remotely determine your MAC address. In the blog post I show how.

Skyhook knows where your access point is because at one time they drove by and mapped it. Google is probably collecting the same information from their street view vans. All you need is a laptop with a GPS receiver to log coordinates and MAC addresses.<p>So why not do it yourself? <a href="http://wigle.net/" rel="nofollow">http://wigle.net/</a> is a public access point MAC address mapping site run by community contributions of location information.

Does this mean that if you upgrade your router and put the old one on eBay and sell it to someone across the country, Skyhook's data is inaccurate (until they next drive by)?
