No, that is the client side. I went back and looked at the documentation, I was wrong and conflated two ways of doing it:

- X forwarding over SSH: this only requires changing X11Forwarding in OpenSSH sshd's config

- Plain X over network, which is secured with `xhost`, insecure, and needs transfering the magic cookie or other authentication information

So, not nearly as complex to setup as I recalled, though it's much simpler to run a nested wayland compositor (which waypipe does) than a X11 server (which xpra does). The difference between X11 and Wayland remote access thins when xpra is involved.

that would be the client side
