No. It is using a central “well known server” and requires internet.
Test:
* Does it work in an airplane?
* Does it work in a submarine?
* Does it work in the mountains, when a thunderstorm is approach and you need to share the GPX?
Basically my Garmin Edge and iPhone can do this. Magic-Wormhole fails in all test cases.
Implementation shall be able to negoiate a connection locally (e.g. Bluetooth) and upgrade to peer-to-peer WiFi if need (Garmin doesn’t need that part, GPX are usually smaller than 1024 KB).
