I've been in IT for coming about 18 years, working with end-users to one degree or another the entire time, and I've never met anyone who didn't understand that the apps they used under Citrix, RDP, or VNC were running remotely and just being drawn locally. They may have been frustrated that they couldn't access local resources (this can be good or bad), but few if any of them thought the programs were installed locally.
It should be dead simple for most people to use a remote desktop capability without much thought on how to set it up because most people are not interested in anything other than the apps appearing on their screen. Microsoft has refined this well enough that it's used in enterprise environments large and small with enough auto-configuration that it will adapt to the local capabilities but can be overridden by a power user if so desired. Anyone who wants to see Microsoft's dominance at least challenged should accept that this is the way it needs to be.
I understand that X does its job well. But there are those who believe that the system in place does not do it well enough. Wayland's devs are in that group and are trying to address it. What concerns me is the group of people who refuse to accept that it should be done any other way and actively try to shoot down alternatives, even before they've had any real chance to use it. That contradicts the foundation of the open source community.
