Another solution, for the hardware hackers among you would be to use a
small power converter (aka "wall wart") to keep a relay closed. The contacts
of the relay can be read using one of the control lines of a serial port
or a joystick port.
Similar devices can be used for mechanical thermostats (over temperature)
water detection, fire alarms, etc.
Sample (meta) perl code would be like:
do {
#
# read_the_correct_bit_from_the_port is a subroutine to read the
# bit set by the relay. Returns 1 if closed 0 if open.
#
$x = read_the_correct_bit_from_the_port();
if ($x)
{
sleep(60);
next;
}
#
# Shutdown the system
#
system("/sbin/halt");
exit 0;
} until(0);
