Indeed.. but you're still faced with the port enumeration problem (plug 4 
of those into a hub, and which one is #1, #2, etc.).  Also, without knowing 
more about the details (I'll talk to Flex) of the USB driver, it may not 
necessarily be well behaved in this application.  The statement:

Specially designed USB to parallel port adapter for the SDR-1000. Custom 
software offloads control processing from the PC to improve performance.

is "scary."

And, then, there's all the other potential problems (multiple instances of 
PowerSDR, audio routing, etc.).

I'd rather spend my relatively few hours of available time working on 
phased array software, not on radio software.  At the current time, the 
SDR1000 isn't a "black box" radio with well defined inputs/outputs, unless 
you packaged it with a standalone computer, and then, it's well over the 
$1K/radio target price  (probably more like $900+$400).
