Giving power to the user in front of the screen

Modern desktop computers running Linux have a sort of double personality that they do not usually share with Windows-based PCs. On the one hand, they are used as single-user workstations where the operator is granted full access to the machine resources, and on the other hand they are also real servers.

Of course there is no reason why a network user located far away should have free access to our machine's audio device or, much worse, to the modem configuration.

With Linux rising popularity in the desktop market, we need a way to distinguish the "user in front of the screen" (better named desktop user) from the "user from far away" (better named remote user), and grant them different rights. This is how I solved this problem for my local network of double souled computers.

GNOME Shell vs. KDE Plasma Graphics Tests On Wayland vs. X.Org Server

While KDE developers aren't yet ready to declare their Wayland session the default, in my experience so far it's been working out very well but still routinely will find application crashes in Kate and the like when testing under the KWin's Wayland compositor.
