Nice to see you're started some dev work for Maemo. That makes me jealous, as I sadly didn't get round to it yet.

Anyhow, I have feature request - you could add readings from liblocation library (I reckon), that are GPS and - most importantly to me - GSM network, ie. CID, LAC, MNC-NCC etc.

I also look forward to see py source file so I could get some inspiration for my own work.

All in all, great job! :)
