It's been discussed before here.  I wonder if the whole shebang could 
be wrapped up in an FPGA.

The Backpack drives pretty much did that via the parallel port.  The 
unit had an FDC (National 8477), a uP and a few K of RAM.  You sent 
it commands to program the ports on the FDC directly, which seems to 
me like the best way to go for maximum flexibility.  Let the host 
figure out what to do with the raw data.
