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!
