Along those lines are Lyrtech's boards (the Small Form Factor (SFF) SDR) 
and TI has something similar. These are almost all FPGA-based SDR 
devices, and I'm not sure what kind of software you get with them to do 
any communications. And they are very expensive.

Gary's new design uses an Intel chip, though I'm not sure where they are 
on production. I've seen them work, though, and they provided a nice 
demonstration of the KUAR at the IEEE DySPAN conference in Dublin last 
year. I hope to get them back for this year's, too.
