Skyhook is creating a concurrent positioning system that can be used in dense urban areas where GPS may not reach. Designed to use Wi-Fi access points to triangulate position, Skyhook is touting this tech as a system that can work alongside GPS systems in order to maintain constant location information in any situation. Thanks to the ubiquity of Wi-Fi, the system seems like a good idea and it can work with just about any 802.11 device, meaning your handhelds and laptops can become local positioning units without much trouble.
