Location-Enhanced Computing Applciations with Place Lab

Place Lab is a software base and a community-building activity that facilitates widespread adoption of low-cost, easy-to-use user positioning for location-enhanced computing applciations. Native code is available on multiple platforms (XP, WinCE, Linux, and OS X) , access via JNI is possible and some sort of framework is available to build location-ehanced application based WiFi positioning. I could not find the requirements, but It is the first WiFi auditing software that more or less correctly runs on my Dell. However, it fails to retrieve any information on the iPAQ 5550.
