The MERCURY board looked intriguing to me, but it's real-mode only, 
which makes interfacing to a DC quadrature
 receiver a bit awkward.   For my application (radio astronomy) getting 
the most bandwidth up to the PC where I
 can "fiddle" with it is most useful.   But I fully agree that an FPGA 
is as legitimate a CPU to host SDR software as
 a Pentium D :-)
