 We have an FPGA-based platform for channel sounding and signal 
reception at 100MHz with requirements similar to the one you've 
described.  We're willing to release the code (FPGA and host-side) if 
there's interest in porting it over to the USRP hardware and the 
gnuradio project.

As a sidenote, we are also in the process of implementing a gnuradio API 
anticipated to be working in the next month or so.  We'll be making it 
public in the next couple of weeks and would appreciate input.
