I am not sure so sure. I think that Doug reminded me that I might have a
switch/router UPS with no servers on it, and how am I supposed to monitor that
then using my idea?
Quick fixes I can think of is
retain old usb/serial monitor system
put a homeplug on it with the network cable plugged into a server and
run some software on that server to monitor it.

I know it is a different set.
I know powerline networking has not caught on, but I think that is only because
there was no need. I do take it exactly as a starting point, and I used that to
avoid redesigning a new protocol and hardware.
