You may have lost me on the "3 ports" thing... You're saying that on Unix-like operating systems there is actually a 3-port interplay to VNC? I assume you mean if using HTTP also, that there is a separate port used for the web server, VNC, and then X Window system traffic? That does make symbolic sense.
