It is reasonable to want remote desktop access. I am unfamiliar with the RDP technique you raise, but expect it could be achieved through VNC or similar systems.

X-Windows is itself a weak response to remote access. I have memories of trying to use Oracle Forms over a modem connection to uni, and finding it far inferior to VNC connections to work systems - effectively unusable.

The remote-windowing mechanisms of X-Windows are coupled to aspects of X-Windows that Wayland was created to overcome. The video 'The Real Story Behind Wayland and X - Daniel Stone' discusses this.

Microsoft Windows does not do remote-windowing in the X-Windows sense. RDP is not Explorer. From what I read, a RDP-like-thing could be built, and Wayland would not get in the way of this. I think the Wayland team make a clear case for why this is out-of-scope for them.

this is sort of exactly my point but inverse - X windows is awesome on a lan & due to the 'native' support for individual applications, but there is definately huge room for improvement w/r/t display protocol performance / latency issues which are largely a result of relying on X server drawing architecture

don't throw the baby out with the bathwater, in other words

But this is the thing, X is not network transparent anymore. Basically no app created in the last decade use the native rendering libs of x, and thus what happens over the network (moving bitmaps) is much worse than what a decent video streaming algorithm could do.
