I'll check out the link this afternoon. I like the idea of
notification. Particularly if it's done through a pop-up dialogue box.
As to rebooting every 30 minutes, I was thinking about that earlier. I
think it would be best to halt after 30 minutes of usage rather than
every 30 minutes. Suppose someone starts up at say 1:29. They would only
have one minute before shut down. If it was after 30 minutes of use they
would have until 1:59.
