MyLoki is a web-application that automatically broadcasts your location using the Loki WPS (Wi-Fi Positioning System). The service uses nearby Wi-Fi access points to triangulate your location through a downloadable toolbar.
Location information can then be broadcast in a number of ways: A hosted MyLoki page that shows people your exact location, a dynamic map widget, an embeddable badge, or through integration with social networks and web-apps such as Facebook, Jaiku and FireEagle.
The service also creates a dynamic feed that integrates with any GeoRSS service, such as Google MyMaps. MyLoki provides the option to enable or disable each broadcast item. For privacy, most only show the city the user is located in. The embeddable map provides the choice between country, state, city, zipcode or exact location.
