 that would suffice perfectly as a development platform, such that
then obtaining smaller lower-priced dedicated hardware, such as the
AD6720 (ARM7+DSP) and porting the USRP-developed softwawre, would be
an easier step.

 the $40 to $50 cost of GSM "modules" is just too much.  the present
situation is, thanks to the "proprietary" nature of GSM solutions,
that free software is entirely locked out of the low-cost options ($10
to $15) involving DSPs and baseband front-ends.

 so - yah, regardless of how ridiculous it would look as a quotes
handset quotes it'd be a damn good start.
