While I'm not sure what changes Option has been allowed to make to the Gobi firmware (an Option engineer told me they can't make many) the Gobi devices expose only one AT port, a GPS port (that can't be used for AT commands), a DIAG port, and a QMI port.
The DIAG and QMI protocols are proprietary and only partially reverse-engineered. QMI requires a proprietary, closed userspace helper library for things as simple as SMS and getting the current access technology (ie GPRS, EDGE, UMTS, HSPA, etc).
So going with a Gobi (even if it's coming from Option) is a strange choice for a project that built it's reputation on openness. Especially if the modules don't support a full suite of AT commands on multiple ports, which the Gobi parts don't with normal Qualcomm firmware.
