[Hardware] Fully unrolled RC5 on FPGA

[Martin Klingensmith]

It is quite possible to fit an RC5-72 gate on a cheap, low power FPGA 
that a student (myself) can afford. It is a very different type of 
implementation and I haven't yet done it myself to figure out the good 
and bad points (I'm estimating that it won't be very impressive).
Regarding discrete logic, do you have a large air-conditioned room and a 
500 amp 5v power supply? One would be mad to attempt it ;-)
