Iroh's protocol can figure out if the devices are on the same LAN and avoid going over the internet. It can work without a discovery server too -- i.e. completely LAN.
Bluetooth is also very slow. Airdrop and Localsend achieve speed by using local wifi networks. The problem with Localsend is that the user themselves need to manage the creation of the local network.

bluetooth is local. Actually, I realise I'm being facetious since I've not managed to get Apple bluetooth to connect to anything non Apple yet.
