Which is a bit heavy on the power side...  :-(

Makes sense to me.  I see I'm likely to use two approaches to 
operating a SDR in the shack.  For common modes, I would like to run 
detatched from the radio, so the on board processor (be it Blackfin 
or whatever)  does the heavy lifting, and the display and audio data 
are sent across a network link.  The need to separate is a space and 
comfort issue.  The shack here lives in a tiny space where it gets 
cold in winter, so a remote user interface on a network connected PC 
would be a nice addition.

However, there are times where someone might develop a mode on their 
PC to test (or I might even learn the art of DSP programming 
myself!).  In these instances, we would need to be able to bypass the 
internal processor and send raw data to the PC for processing over 
USB2 (assuming the current Ozy specs).  As I said a while back, 
flexibility is the key.
