I just saw Digi is coming out with XBee Cellular modems
. Adafruit has sold some form of cellular modem for robotics projects over the years, but this is the first time I believe we can get it in XBee form.
Would the Propeller boards (Activityboard, BOE) that support the XBee socket eventually support wireless connections through these as well? Could be used for building an outdoor autonomous rover bot always connected to the 'Net, even outside normal WiFi range.
