Whats this "shutdown" think you mention...?

Depends on your meaning of LTSP.. I built some diskless clients that 
boot using pxe/dhcp and run an X server connected to a umm.. server 
(that is just soo wrong that way they describe that)

When you log in, you are logging in to the server.. no processing 
happens client side as such, except the execution of the X server and a 
few other scripts... Earnt myself a bottle of JD for making those... (i 
think i know who got the better end of the deal tho eh ;-) )
