I think the advantage of a second webserver for the controlpanel is that the controlpanel is still rechable in case of problems with the main webserver and you can configure your own webserver the way you want and don't need to consider the special mods and configs for the controlpanel.
Is it necessary to run on a different port? Why not a subdomain?
Please note that this may not be practical: I'm just wondering why not.
