There are finally PoE adapters that give USB-C power and USB Ethernet. Those should allow home theater devices to be powered and use wired Ethernet. But the ones I have found are expensive, but should drop if there is demand.
I also haven’t found any bidirectional ones yet, even though the hardware (except maybe the negotiation chip if it’s pure PDE) should be able to support it. Would be really nice for development of PoE devices to just hook up one dongle to my laptop.
