GitHub - wtlnetwork/muon: Steam Deck ad-hoc networking plugin for Decky.

This plugin allows two decks to connect directly to one another, allowing multiplayer lan games to work without any wifi network available.
I remember before the Steam Deck was released, and people were discussing all the potential capabilities of the upcoming device, it was often asked if this might be a feature. Of course, there were the usual "It's a PC, so yes" answers, but the more accurate answers along the lines of "If it's not, someone will make it work" are finally coming true now.
I know people have managed to do this manually for awhile now, but honestly it sounded like more trouble than it was worth, especially when many people can just toggle on a wifi hotspot on their phone.
This is great though, finally a nice user friendly option.
