If I understand the problem correctly, here is a possible solution: create
another daemon (mged) that connects to the high end UPS and in turn listens on
multiple sockets, one for each outlet.  Each socket would simulate a simple
UPS.  There would be a NUT driver for each simulated UPS that connects to a
socket on mged.
