11/26   When I do "finger @hostname" or "w" I can find out if the other
        user has typed something on his tty or not by looking at the idle
        time. But when the other user is using xterm, his tty isn't displayed.
        How do you detect that?
        \_ Hint: you don't need a tty to log on.
        \_ You want help stalking someone?  You could email them, you could
           call them, you could send a talk request and say, "hey, are you
           idle right now?"
            \_ Yeah, that wouldn't be annoying or anything. :)
               \_ Makes it hard to stalk, huh?  Or hey, maybe a write request?
                  That would be tough.
