I didn't think is was anything to do with RSA. "X10" or "XIO" was a remote control system for the house that Heathkit once marketed before Sears or someone else took over. It was a control system that communicated through the power wires of a home, making the external power plugs on some homes, portals for mischief. ;)

It was a nice idea, overly priced, and not secure.
