Dan, Not sure if this is what you had in mind for your article, but you might take a look at www.loki.com . Loki is a Firefox/IE location toolbar, and is based on the idea that "ambient" wi-fi can be used to accurately determine location (see Placelab, Microsoft "Locate Me").
Loki provides a useful geotagging tool, lets users share location information via email, and enables content search using accurate location as a contextual filter. Finally, Loki invites users to explore the value of location on the web through the creation of personalized "location channels".
