At the risk of causing a matter vs. antimatter paradox that would end the world as we know it ... Is it possible to host a Debian repository on a Windows server?

We have some applications which are available for Windows, Mac OS X, and Linux. Our web site, from where the application can be downloaded, is a Windows Server 2008 box running IIS 7. That is not going to change, and I would like to avoid having to purchase another server and/or domain.

I would like to take advantage of the Debian packaging system so that I can just instruct users to add our repository to their software sources, and then they can install, get updates, resolve dependencies (some of which are not yet in the stable/main distributions of my target platforms), etc.

The instructions I can find on the internet require linux-specific tools to create a local repository, but are unclear as to whether or not that can be copied to an FTP site as is, or if it requires some local daemons to be running or something.
