dear gnuradio developers,

i was searching on opencores.org to see if there was a SoC that
incorporates an FPGA(-like) device with an open core, and i
accidentally encountered the above USB-FPGA board.  it has a Cypress
CY7C68013A/14A 480mb/s USB-2 Microcontroller and a Xilinx Spartan-3
XC3S400 FPGA.  it is also accompanied by a developer board:

the price for the USB-FPGA is an incredibly-low $EUR 70, and the
developer board is only $20.

so my primary question is: is this USB-FPGA board (apart from the
issue of connecting to A-D / D-A boards) suitable for use to do an
802.11b transceiver?  is it fast enough?

many thanks,

l.
