Part of the idea is to be free from a local PC and free from USB.  We'll 
probably need the FPGA fabric since a configuration with this board 
probably wouldn't have an Ozy. I didn't mean to restrict it to the same 
I/O configuration as Ozy (e.g., a port designed to drive an SDR-1000).

If a Xilinx Virtex-4FX were used as the core processor and FPGA, 
reference designs exist with 1 Gbps Ethernet. I suspect one of these 
could be leveraged (e.g., Avnet's DS-KIT-4VFX12LC at http://em.avnet.com).

Of course, the PowerPC cores in the Virtex won't run WindowsVista, but 
might run MontaVista :-)

Neither simple nor cheap, but perhaps interesting?
