Hi Brad,

It's interesting to see different variants on how wi-fi could be extended. I came up with an idea to embed the zip code + 4 of an access point, into the SSID. For example my access point has a SSID of theboxfactory:60607-3533. With this simple SSID 'tag', any application could potentially extract its location and then derive local information. You can read a little more detail about concept at this post http://theboxfactory.net/weblog/index.php?p=5
