I have heard they are either working on a similar thing for Wayland or already solved it.
This looks promising, but I have not used it before.
waypipe is a proxy for Wayland[0] clients. It forwards Wayland messages and serializes changes to shared memory buffers over a single socket. This makes application forwarding similar to ssh -X [1] feasible.

Yep that’s why I use KDE. It has nVidia support for Wayland.
