And use xev to figure out the keycode of an unused key on your keyboard you can easily access (like multimedia keys). Then you can activate it when leaving your spot or when that creepy guy from accounting tries to look over your shoulder. You would probably need some window/session manager that supports "global key shortcuts". I like the bluetooth idea too, with the caveat that the range might not be sufficient. There's an article about it here: <http://johnny.chadda.se/2007/08/09/lock-and-unlock-your-gnome-screensaver-using-your-bluetooth-phone/>; I don't use bluetooth at all, so can't help you with the FreeBSD specifics. -- Mel
