Interesting. I cannot find anything about this limit in the X Window System Protocol specification, though. Do you have any example of such software? > Does your ThinLink support these 2000 sessions all at the same time? > or are > there just 2000 configured to run? What kind of sessions are they?

We support 2000 concurrent Xvnc sessions, although we haven't yet seen any system large enough to handle them. We have tested up to something like 250 sessions or so, but the port number layout etc should be fine up to 2000.
