I looked into xdg-desktop-portal but AFAIK it doesn't provide a real RDP API (e.g. it user-prompts for devices or screens choice and has no way to do that in the background as a real RDP server daemon would require). That's why I was considering the internal interfaces.

I still don't understand: if I have two users connected to their respective gnome-shell (or plasma shells) implementing Wayland, how do I tell one process launched by perhaps a third user to capture one user's instead of the other's desktop?
