[J-core] Amazon EC2 fpgas?

It's certainly possible, but I would think the utility is probably very
low. The FPGAs on Amazon appear to just be attached to the host through
a shared memory bus via PCI express. This means you don't have a serial
port, storage, memory, network etc. All of that would need to be
emulated on the EC2 host which doesn't really help you very much except
for having an the CPU in hardware. The Amazon FPGA product seems to be
more for "I need to compute a specific thing very fast" as opposed to
hardware development. Also since the instance sizes are 2XL or 16XL
only, getting a one of the cheaper development boards linked on the site
would probably be cheaper than running an instance for a month (based on
pricing for m4.2XL on-demand being $350 for one month).
