Yeah you get it. What triggered it for me is there is a PoE standard for automotive that can deliver 50W over a single twisted pair. If you bumped that to 125

Yeah you get it. What triggered it for me is there is a PoE standard for automotive that can deliver 50W over a single twisted pair. If you bumped that to 125 to 150W then it would yes be great for residential for all the reasons you can think of. Cheap cable, crimp connectors. No license required to install. Low voltage and generally much safer than 120V and especially 240V. Consider with power negotiation a default max power of a few watts which isn't going to start fires. Wanna replace a light fixture? Unscrew the old one, unplug it. Plug the new one in and screw it back on. Also imagine kid safe outlets that are standard world wide.
