Project mention: LAN Mouse is a mouse and keyboard sharing software | news.ycombinator.com | 2024-01-02

You might take some inspiration (or some code) from https://github.com/htrefil/rkvm
I've used it and it works pretty well, is written in rust, and it has one big advantage - by emulating the keyboard and mouse at the linux evdev layer it avoids touching any of the desktop-specific apis. (It also has encryption, though over TCP so has issues with managing connections. I think your choice of UDP was a good one)
