The range that Corne refers to is the port assignment range for X displays,
and is not actually enforced by any X implementation that I am aware of.

That is of course to be expected since, as I said, there is no technical
limitation on the number of port numbers available to either of X or VNC,
and since your software is based on VNC.

Just to clarify - there is no intrinsic limit on the number of VNC sessions
you can run on a system, just a limit on the automatically-assigned display
number pool, which is easily extended, and of course your system's resource
constraints.

Cheers,
