That being said, there are hints that the way systemd is heading will support "multiple seats". Whether that means multiple video cards, keyboards and mice plugged into a single box I don't know. I do know that for a long time UNIX has been doing on one box, possibly chrooted, what it takes many virtual instances of MS-Windows to do: dns, dhcp, smtp and more -- and all without needing virtualization.
So it might be that the 'multi-seat' is really a GUI version of what we were doing with PDP-11s back in the 70s and 80s, that is having many terminal plugged in to one box and many people logged in simultaneously and making use of the multi-processing and process separation capabilities of UNIX.
c't ran an article on such a Linux multi-seat setup some years back, possibly more than 6-7 years ago. AFAIR, without virtualization.
Now, with Linux and things like CGROUPS we have better control over that separation and resource management than we ever had with the PDP-11 and the VAX :-)
You should have moved up to real operating systems :-) MVS and TSO never had any problems with that.
