Has output for FPGA been considered?
VHDL, Verilog...

This is an interesting idea. I'll try to research what can be done here.

Maybe consider first the lowest cost programmable logic boards-
something that hobbyists would use, ie: I just got a $30 MAXII kit off ebay.
Perhaps you could provide a bundle that works together and get this into the "MAKE" ecospace.
