Well, while you're at it, why not add a hard drive, a graphics
accelerator, a scanner, an ethernet adaptor, a pencil sharpener, and a
juicer attachment?

Jesus Christ! Can't anything be simple for you, Richard? This is a
SOFTWARE exercise, not a hardware one. You keep wanting to throw an
entire government beauracracy at the simplest of ideas.

Just specify a challenge and let people go at it. Screw the speed! Screw
even judging the resultant code based on their relative operating times.
The real judgement will be on the cleverness of the hack anyway.

Oh, you think so!?!?

No, I think its already suffered from WAY too much.
