Of course.  It's just 1s and 0s, you know?  :-)  But we already have CP 
shutdown commands for RSCS, TCPIP, SFS, and DIRMAINT:
 FORCE RSCS
 FORCE TCPIP
 FORCE DIRMAINT
 FORCE VMSERV

IF the guest supports signals, they will be invoked without having to 
explicitly SIGNAL SHUTDOWN.

Not having tried it, I would suspect that Romney's SHUTTRAP program could 
be used (loaded as a nucleus extension) to do what needs doing, whether on 
GCS or CMS.  It could even send a message to your shut-me-down-nicely 
virtual machine that would immediately begin the shutdown process for the 
affected server.
