All of which occured a few years AFTER the X-10 patent expired. Prior to
that the other 'brands' that used X-10 technology were assembled on the same
assembly lines as those that carried X-10 labels. Aside from the labels,
they were identical (except for the CM10A made only for IBM).

Then why claim it's a security feature? If your neighbor is determined to
"gaslight" you, it can be done with X-10, UPB or Z-Wave. Of course, the high
price of UPB does serve as a deterrent.

And why is it that the same people who complain the most about poor X-10
signal propagation also worry so much about interference from the neighbors?
I can understand it in Europe where there may be hundreds of residences
sharing a utility stepdown transformer but in N. America it should be easily
dealt with.
