Greg,
The 'subnet' is generally limited to the particular power circuit
the EOP device is on, it generally cannot jump to other power circuits, most
residential households only have a single power circuit that makes it ideal
to use, however in larger buildings these devices start to fall down as they
usually have several/many power circuits. I believe that you can get
hardware that overcomes this limitation but I suspect that the cost would be
prohibitive for a general practice.
