Higher accuracy is one of Place Labs less spectacular goals. According to the Web site, the group "endeavors to provide planetary-scale and privacy observant user positioning."
Were not sure how Place Lab might deliver global coverage outside of major cities, even if the system takes advantage of emerging long-distance broadband technologies such as WiMax. Well buy in on the privacy concept. Place Lab doesnt require checking in with a central service, and it would take an extraordinary effort to begin tracking Wi-Fi users by their MAC addresses. (Not to mention access to a huge array of Wi-Fi hotspots.)
The Place Lab client is available for Windows XP, Linux, Mac OS X and Windows CE/Pocket PC.
