Both of them have their own small displays, and the faster box (Devuan)
is also attached to a big TV for presentations. The presentation room is
kinda small theatre and the audience tend to sit far away in the last
rows. (So they can easily smoke & drink while I talk.) And apart of my
presentations everybody can sit in a front of local display, no problem
with that.

It's complicated at this stage for total beginners in Linux. That's not
my point. As I said, I already have two machines, each as dual-boot,
wired in between, each having its own display, printer, etc. So it's
just a proper software package issue.

PS: I have already made some tests with remote desktops in my home LAN
(mixed Debian and Ubuntu machines, also in dual-boot combinations). And
I only had to add x11vnc server packages to them, and used clients I
already had on those machines ("Vinagre is a remote desktop viewer for
the GNOME desktop"), and it works! So I planned to do the same with
Devuan. Nothing else than that.
