I tend to agree, though I can think of situations like a public demonstration PC locked into a box, or schools where you don't trust the students, where making rebooting/powering-down difficult is beneficial. I think you also have to take care of other matters if you allow people to reboot computers that aren't their own, so that they can't easily boot from other media, or change boot parameters, to bypass your security. -- Don't send private replies to my address, the mailbox is ignored.
