[hpsdr] Potential New openHPSDR Project

[David McQuate]

I've been eyeing Beaglboard, and Hawkboard for over a year now, but 
simiply didn't have the time to do anything but look. There's been an 
incredible amount of work done all over the world on both boards, and 
especially Beagleboard, with Linux and Android OS. DttSP and sdr-core 
have been ported and run, I believe. In a nutshell, I'm very interested, 
and wanting to contribute!

I think Hermes should be considered, as well as the Atlas-bus-connected 
components. I'd like to see an LCD, maybe touch-sensitive.
Let's continue the discussion!
73,
Dave
