Hello,
Sorry, but I misunderstood the requirements. I don't need to use any virtual desktops(as in desktop environment virtual desktops). There is a single X server which has 4 physical screens attached to it. So, in the current setup, if the resolution is 4000x1000, then the first monitor displays the first quarter of the whole display (say from pixel 0 to pixel 1000 on the horizontal and all of the 1000 vertical pixels), the 2nd monitor display the second quarter and so on.
So what we need is this: a vnc server running on this machine.
4 vnc clients running on the same machine. each one is displayed on a different monitor. each one should display ONLY a quarter of the screen. So, basically, I want that on the monitor#1 to have a vnc client displaying only the first 1000 horizontal pixels and all the vertical pixels. On the second monitor, I want another vnc client which will display horizontal pixels 1001...2000 x 1000 vertical pixels and so on. The vnc clients should have full access rights, just like there is no vnc involved at all.
However, I want to see everything that's happening on the screen on a remote vnc client, which initially is connected read-only. If this remote watcher sees that something goes wrong on any of the 4 monitors/quarters of the screen, then he should take control.
Any ideas and suggestions on implementing this are welcome.
Thank you.

What you're describing below (server1:0, server1:1, server1:2, etc) is
called an X11 "display". Each X11 display supports one or more "screens",
which are addressed by X11 applications as server1:0.0, server:0.1,
server1:0.2 etc. The current VNC Server for X11 will make these screens
available as separate VNC servers on ports 5900+display, 6900+display,
7900+display, etc.
