But DISPLAY is already used by X... If we are going to be using X clients with 
Wayland, then there might be problems... Also display can also be something 
like, using a remote display :9 on I don't know 
how Wayland would react if that was the display... If its supported, Wayland 
probably would need to invent a new variable...

And as far as xhost goes, I know that Wayland is local only, but I guess I was 
asking more about Wayland security in multiuser environments using the switch 
user feature, and how to prevent authenticated users from spying on each 
others Wayland sessions.
