Imagine the open sensor net

Energizer USB Charger

I picked up a cheap little USB charger while waiting in the Airport for the Virgin Coach to Milton Keynes (follow the twittes going forward). And I noticed it actually contains a sensor with a private API so you can monitor the recharging progress in a application. This is cool but the application only runs on Windows and Mac so no chance of a gnu/Linux version anytime soon then. But it got me thinking, how interesting would it be if the sensor did have a open API which you could query? I could tie that into a screenlet/widget instead of a crazy separate application. Anyway dreaming over, this device makes a good addition to the Moxia USB Cell batteries I already own. Only my work Nokia N80 is the only item I carry with me when traveling which doesn't charge off USB. Everything else is USB powered.
