Andreas,
what webserver are you using to run your Joomla-site? Is this a Nettalk-Webserver or an Apache (due to PHP)?
The Nettalk Multihost allows you run several Nettalk-Webserver, ech one being compiled to a DLL, instead of an EXE. However, I doubt that you can combine the Apache into this setting.
But if you run an
Apache, you then can set its
vhost.conf to point to any other Nettalk Webserver (.EXE), just as you intend.
There is an excellent article by Benjamin Krajmalnik in Clarion Magazine:
Apache As A Reverse Proxy For Clarion Web Servers
By Benjamin Krajmalnik

Summary: Third Party toolkits such as Handy Tools and CapeSoft's NetTalk/Self Service have
enabled Clarion developers to write special purpose web servers. But how do you go about
hosting these servers, particularly when you have more servers than you have public IP addresses?
Benjamin Krajmalnik explains.

Just to make sure, the Nettalk Multihost solution is much more convenient, its the first choice to run multiple Nettalk Webserver. But if you need to maintain an Apache at the same IP-Address, then you might be better off with Apaches vhost-option.
