Can this be a made to work as an adapter to play older, raw UDP multiplayer games with random strangers? E.g. telling someone in Twitch chat “bro 1v1 me in CS1.6, here’s my Iroh ticket:”, they put it into their “InstaFrag NetDriver” Windows Client and you both launch CS1.6 and just start playing in an ad-hoc p2p lobby.
With Tailscale this use case is very cumbersome as you’d need to add them to your tailnet and configure access controls to make it an ephemeral connection.
