It's the only option, as far as I'm concerned.  Sharing an Emacs process
with some other user simply doesn't work at all (as anyone who has tried
it will know, I think).

Back when I tried it, those issues didn't even have time to show up.
Instead we quickly bumped into issues with the "single keyboard mode",
and other similar "modal" problems.  Or the unexpected sharing of the
kill-ring, ...
It's just hopeless.

Indeed, the first thing I did when someone tried `make-frame-on-display`
to display their Emacs session on my display (back when we tried out
this new feature), was `M-x shell`.
