And takes the latest value of info needed to send back to DMZ.
It appears that none of this is original. Oh well. I guess I read it over at EVTV and recalled it in my own way .. does that count?

From the description above:
- substitute the DMOC645 AC controller for the dsPIC
- substitute the GEVCU for the DMZ, and the communication is CANbus
- substitute the bluetooth/802.11 wireless board as the Firewall, communication is I2C ( I think) from the board to the GEVCU

One of the good parts is that the GEVCU is open source but the bluetooth/wireless board is not. I think I had mentioned that some time ago - the code, the board layouts, et al. I'll go through the forums when I get a chance and see if they had problems somewhere and would do it differently next time around.
