Maybe I'm missing something, but if you lose power then either the other computers are on a UPS of their own (or are a laptop) or they are already down. Unless of course it's just local to the core, knocked power cord out or tripped a breaker, in which case the other systems will continue to have power. If the other computers have their own UPS it makes sense for each of them to monitor their own.
The ups/controlled shutdown on power loss is a good idea, I'm just a bit confused as to the benefit of trying to shutdown other systems when you lose power on the core.
