Wouldn't it be better
If all PC's in a large business were so equipped to be used in such a way. My home PC is on 5-6 hours a week, if that. That isn't going to add much to anyone's proceesing power. My work computer is on 9-10 hours/day and many times it is just logged off in the evening, because of the 5-10 minutes of network scripts run everytime it is turned on take over 5 minutes of time to run and make the computer useable.
