I understand that you plan to redistribute the application on a larger scale, but would that not be a part of the configuration process anyway? For example, your potential users would need to things like the application and system directory, which could vary from machine to machine, as well as database information (for external and localhost database servers). Some hosts only give access to the Web root, whereas others allow files to be outside of the Web root (which is where I store my system and application directories). I only actually store things such as scripts, images and CSS in the Web root, along with the index.php. I trust you've taken this into account, as configuring the config.php file dynamically would never have occurred to me, so you've clearly put a lot of thought into it.
Another thing to bear in mind, is that I'm not sure if this problem is specific to the ISS platform only. My server is running Debian, yet AUTO doesn't seem to work for me either; I've no idea why. All I'm saying is please be careful. One thing I've learnt with Web servers is that the are no guarantees, unless of course all of the servers are set up identically.
