BTLE Device Handoff is another name for the BTLE Audio multi-device stream control. Read a little about it at the Bluetooth LE website[0] -- you're looking at a combination of the Audio Stream Control Service and Telephony Bearer/Call Control working with the Coordinated Devices setup. One of the goals of BTLE Audio is that you could be listening to music at an airport from your laptop and an announcement can chime in over your music to tell you that your flight has been delayed once again, then hand off the audio stream to your phone when you get a phone call from your significant other asking if you're going to make it home in time for dinner (you aren't) Miracast is an open standard, and there's multiple open source libre DIY implementations of it -- you can even use it from Wayland now.
