matt, attiny is just a little microcontroller, like a pic, but if you know an adc that handles floating ground that would be useful, I don't know how to search for it.

Here's a page that provides some more ideas, a basic stamp based battery individual battery monitor. He has plain optos on each battery that draw a continuous 25ma (maybe) so not 100% ideal or easy to disengage in a sleep mode, but still plenty to think about: BATTERY MONITOR

I also have to think that too many chips and a network will add to the "leakage" power consumption just as a voltage divider would. I wonder if you can make an auto-ranger out of a 4051?
