I don't think you have that kind of control.  When you attempt
to make contact, WoL (if enabled) would cause the target machine 
to wake because of the incoming packets.  Either you send a packet 
to that host or you don't.

Another issue that may need to be looked at is that the frontend
doesn't currently attempt to re-establish a connection to the 
backend, after communication is lost, which is annoying in 
general, but could make it impossible to implement this idea.

There might be varying degrees of success with saving state to 
disk with the current suspend-to-disk options, as mentioned by 
Henk in his post.
