Just a slight hijacking of this topic,
	I have a little EPIA server acting as firewall, npt, dhcp, dns,etc,etc. 
Now even though it doesn't pull a lot of power, I don't want it running 
all the time, it has something to do with missing ice caps. So I want to 
build a button that attaches to the machine via, say, usb that when 
pushed shuts the machine down. By a button I mean that sort of emergency 
shutdown button that is usually red and used in industrial control, the 
sort of thing the hero always has to push to save the heroine/world.

	Does anyone here have enough hardware design knowledge to say if this 
would be easy or not and as to whether I should just lower my sights and 
stick to the three finger salute or the "normal" on/off switch?

	Regards,
		Andrew

p.s. The main reason driving this is that the wife never turns the 
server off. If I have a Big Red Switch, I can say "But it has a big red 
switch, how can you miss it????"
