Thanks for the explanation. 	Those aren't my definitions, those are pretty commonly \
used, however, in my research on this topic there also seems to be a lot of \
information out there that misuses the terms so I wanted to be clear in my post.

Remote Control / Remote Screen Sharing / Remote Management / Remote Screen Mirroring \
or whatever term you prefer lets you see the 1st computers screen on a 2nd remote \
computer. In the Microsoft world they call it Remote Assistance.

While it may use some of the same technology as Remote Desktop ( also called Terminal \
Services on Windows ) is very different in that Remote Desktop provides multiple \
remote users access to a desktop session.

I am aware of this limitation currently in Wayland but was pointed out "Never say \
Never" as work is being done to provide headless support for Wayland through GDM and \
I believe that the KDE people are also working on something.  I've been following \
that link about Wayland thgrough GDM.

The xrdp people are also watching/communicating with the TigerVNC people looking into \
how to provide this type functionality.

Linux is such a great multi-user server so hopefully it is not a matter of if but one \
of when it will be available.
