Question: Has anybody ever, in the history of X11, actually run the 
display on a different machine to the one where the program is?

I realise that X11 *can* do this (hypothetically), but does anybody ever 
use it? From what I've seen, everybody actually uses VNC instead.

My understanding is that X uses a device driver that is specific to the 
display hardware it's trying to run on. I'm not sure why you couldn't 
write such a driver that specifically targets the Amiga's video hardware.

(Or rather, someone *must* have done that to get X to work at all. What 
I mean is, write a driver that takes advantage of the available hardware 
acceleration...)

Yes. personally since 1990.

VNC is just bullshit when compared to X11. The killer of bandwidth is
the lovely decorations & curves. X11 is damn effective to handle the
mouse and rectangular area/basic widget such as radio box. Canva (free
drawing area) is slow.

Yes, I use it fairly regularly here at home.  For example, ssh'ing to 
another local machine and running an application remotely.  In fact, I 
did it just last night, running YaST's QT interface remotely to update a 
firewall config.

Me, and the rest of my team, every day for 10 of the last 15 years.

Yes. Me, for instance.

The whole computer system at our engineering department at university 
did this. One central server. Fun times when an entire class was doing 
the finite element modelling course. And the absolutely atrocious GUI on 
most applications we used put most people off Unix/Linux for life.

Someone probably could, but a different question is whether someone has.

(Also, while I know nothing about the X11 architecture, it's possible
that even with an optimized driver it might not be able to take full
advantage of a very unique display hardware, which the one in the Amiga
might be, because X11 is too generic of an architecture.)

NeXT, wasn't it?

Yeah, you might be right about that...
