Micro,
I've been giving some thought about your post a while back about the government hacking into computers.
Food for thought - put all data on an external USB hard drive - move files so that actual programs are the only thing that show up on the computer - then any time you are not at the computer, disconnect the external hard drive. That would protect your data and still allow you to leave all your computers Folding.
Would not be any more inconvenient than starting and shutting down the computer and would actually take less time.
Just a thought,
Sun :-)
