@Max_P Just to pick your brain and sorry for asking so many questions but what if from what you said nested compositors/clients/etc I could just create a separate virtual screen and have WAYLAND_DISPLAY=wayland-1 (or 0:1) wouldn't I be technically be able to capture that and project it for my needs?
I guess I'm just jumbling/reorganizing my mind with this new information. I feel like the question would be "can I create a virtual monitor within a parent session?"
Anyhow, thanks again!
@Max_P Anyhow I think I should be good. That was all super interesting looking at the freedesktop documentation it does answer some things I was wondering about myself.
Now I don't think I feel in the mood to toy with creating my own display manager, maybe as a pet project but man I can't imagine anyone new be like "so there's a centralized documentation/communication channel for all of this, right?" π
