Will it work entirely locally? No, account required. Will it work well outside of two happy paths in the demo? Probably no.
… how do you expect a cross-device feature to work locally? 0_o
Like KDE Connect which uses only the local network.
P2P, you’re very likely already in the same network and/or have a bluetooth connection established.
Not counting audio I connect across my devices via Bluetooth maybe once every 3-4 years lol. I don’t even think I’ve ever connected my laptop to my phone. Not to mention even at home I’m not always connected to the same network, for eg one part of my house I don’t get wifi properly so might be on mobile data on my phone. I don’t think using P2P is particularly noob friendly.
Apple’s AirDrop (direct WiFi connection) is pretty noob-friendly though.
Android had “Android Beam” via NFC forever ago, too.
