One obvious way is to have the SCO box email root at redhat.box with a
suitable subject.  Have redhat root's .procmail fire off a shutdown script 
on receipt of one of these messages.  

You'd need to do some accounting for the time it takes for an email to get
delivered and acted upon though.  Maybe have some kind of "Hold on, I
didn't mean that!" escape available also.
