Agreed. I'm building a presentation software[1] so it needs to work locally (can't afford lost of connection). But I also want it to be accessible from anywhere. Unfortunately those two things don't mesh that easily.

The tech is getting there though. With things like hole punching or webrtc, P2P is getting pretty easy to implement. Though it's still a challenge to implement it in an actual project.

I do believe that we're going to start seeing quality local-first software w/ great networking pop up more and more soon. I'm working on that, but I'm sure there are plenty others who are doing the same.

Really, why not use Tailscale?
