plazes - global location-aware interaction and geo-information system
‘Global location-aware interaction and geo-information system’ sounds pretty weird but it describes very well what plazes is doing.
Plaze = Location + People. ‘A Plaze is a physical location with a local network - private or public, wired or unwired. A Plaze constitutes of the information about the actual location like pictures, comments and mapping information, as well as the people currently online at that Plaze’
You can register free, set up a place (a physical real place) and can see who is nearby. The plazes-client is pretty small and can be downloaded for the most important plattforms like Mac OS X, Linux, Windows (yes, in order preference).
