I already understand it. :)

an application of this would be in the script that says basically this:
if input = 1
	then echo "go away"
else return
(hokey I know, written like old basic, but it gets the meaning across)

so, if there is no input on a network socket (say your internet) then it sits 
there until someone tried to connect to a port (like telnet) at which point 
it echoes a response "go away". Otherwise, it sits there.

its a very simple way t tell someone that shouldn't be there to bugger off :)

anyway, thats one application I like for it.

another would be like the doorbell that allows port entry.
