It’s probably already been covered, but my 30 seconds of Google-Fu hasn’t turned anything up so bear with me…
Take one OpenMoko phone,Â a geolocation service like Fire Eagle, an online celltower database such as CellDB, and some code to use those lovely d-bus bindings, and you could have a location reporting service that’s easy on the battery and mostly precise in urban areas. If your area isn’t covered by CellDB, then run around with the OpenMoko GPS reciever online for a while to report celltower locations, and you’re sorted.
Use all of the above to create services like Socialight, location based Twittering, rough geotagging for photos (courtesy of Flickr and FireEagle [both Yahoo companies]) , pre-emptive OSM tile downloads, Asterisk routing – you could even implement ex-girlfriend logic to it all, if she were to have a similar device 🙂
Well, I’m sure someone has thought of this already, but I thought I would commit ideas to storage just in case. Once my FreeRunner arrives, I know what I’ll be working on
