How do the new FCC regulations affect, if at all, OpenMoko development? Is the GSM module closed? If so, is the only way to interact with it through the AT interface and c library? Just wondering because it seems that it would fall under the new FCC regulations  that are going to take effect regarding SDR devices.
I don't think there is any effect. All power and SDR related software is on the baseband processor (ARM 7) and is definitely not open source. It will probably be similar for the Atheros WiFi.
