Google explored doing this with devices that connect to each other, specifically Chromecast and their early Google Home devices. I don't think it ever launched but Google did some interesting experiments to test the ultrasonic transfer functions on millions of consumer devices. (I worked in audio research at Google at the time but not on this).
I believe the main problem is that it makes dogs go crazy
- pests 1y agoI might be misremembering but I am 99% sure the early Chromecasts had this. It was a “Guest Mode” for when you wanted to share access to a device not on the network. I don’t think it lasted for long.

I couldn't remember if it actually shipped in anything, but looks like it did!
