Ooh, I love your city. I'm turning red now...

Well, that's a lot of info in one post. I think your project can be done in PBP with no problem. The part that I think is unrealistic is trying to get this device running for a few months with a 25mAh LiPO battery. Let's say that the average comsumed current of your device is 1mA, then with some luck you can run your device for 25 hours. You are taking into consideration only the quiescent currents, but what about the operating currents?

Is this device going to be connected to the USB port all the time? Can you use a bigger battery?
