I forgot to mention: the slave configuration is generally going to be manual, 
unless you segment the UPS output circuits and the networks in a similar 
fashion. I don't know of any PC power supplies that can get some sort of 
identification from the UPS that is directly feeding it, although this would be 
very handy for reducing errors in configurations such as this.

If you had subnets that segregate the A and B groups, you might be able to do 
something with mDNS to find the nearest NUT master, but I don't know if I would 
depend on that unless servers move around frequently.
