I haven't really followed this thread closely, but this seems like an 
excuse to suggest this ...

We should be able to build gnuradio for this using Angstrom/OE. The 
processor (although clocked at a ridiculous speed) won't be very useful 
for for doing gnuradio radio signal processing, but I suspect you could 
use the gr-udp blocks to send data over the network to a more capable 
machine for the actual processing.
