Is the display server(DS) a system wide daemon ? Could two users run
two different DS ? And if not why ? Why two users can run two different
shells (zsh,bash,etc) ? Could two users run two different terminal
managers (tmux ,screen etc) or two different dbuses or two different
windows managers (in X at least) ?

Also could the admin run services that no user wants or uses ?
And couldnt we imagine a lan with thin clients where a user wants
to run a webserver but not the admin ? And isnt fs-sharing a form of
webserver or vice verca ?
