[Hardware] 'success'

[John L. Bass]

	Hi John,
	I'm sure double-checking has been discussed before?
	If you have a log of which work units every user has submitted, and you
	check every nth work unit with another user to see if they get the same
	"residual", could you faithfully determine at least at some point if the
	user was cheating? Even if they try to submit some fake and some real,
	they'll probably get caught at some point. It would indeed slow the
	process down. I don't know what percentage would have to be double checked
	to be statistically valid.

Double checking is necessary to validate both client software and hardware
anyway. That it also detects cheating is just a minor aspect of the rule
enforcement.
