Skyhook Wireless's Loki navigation toolbar uses the company's GPS-like Wi-Fi location system: With coordinates in hand, Loki can feed location information to Web sites that use position to provide results. This could include the simple (maps), the useful (Wi-Fi directories), and the mundane (where's the nearest Home Depot?). But it can also include presence, where you can reveal your location to selected others, and all of you can be plotted on a map. Useful for sales forces, repair technicians, and others.
Skyhook has also added SMS notification, which lets you push your location via a text message to a friend or colleague, and a time zone changer, which uses the current location to set the system clock. Skyhook also says it's improved the speed and accuracy of lookups.
