Brian, that looks to be a great solution actually! I may indeed have Oshpark build me one.
Yes it does require USB power and I've been trying to figure out how to supply that by alternate means. I believe the WiModem232 with OLED would draw way too much current to power from a BCR port though. Maybe a battery solution like you suggest is the right way to go.
