Yes please, send me a dozen ;-)

I have been dreaming about an USRP version 2 with a few Cell processors, 1 GB 
RAM and an FPGA with 256 embedded multipliers and 10 Gbit ethernet
interface and 16 ADC/DAC channels running at 1 GSPS.

But for the short time:
Cell processor
 or
GPGPU
 and/or
FPGA  (just put it in the USRP verilog)

will probably do.

I already succeeded in implementing a big FIR filter running at full speed (64 
MSPS) in the usrp, so I might even be able to put in a complete
QAM demododulator one day.
