How about an FPGA Arduino compatible SDR?

I have been fascinated recently with a new PCB that has been announced - the FleaFPGA:



I am dreaming of an SDR based on the FPGA, but I have no idea how to go about it. If there is anyone out there interested to investigate this let me know, antonywatts at me dot com.

Unfortunately all the development software runs on Windows 7-8, and I have only Macs, so that would present a problem!
