What are your experiences implementing/using WebDAV?

Question

For a current project, I was thinking of implementing WebDAV to present a virtual file store that clients can access. I have only done Google research so far but it looks like I

We use WebDAV internally to provide a folder-based view of some file shares to clients outside of our firewall. We're using IIS6 for this.

Basically, it boils down to creating a Virtual Directory in IIS that maps to each network file system that you want to make available via WebDAV. Set it up with the content coming from "A share located on another computer" -- use the UNC path to the share for the Network Directory value. We turn on all options except Index this resource. Disable all default content pages. Turn on Windows Integrated Authentication (ours is set up using SSL as well). I have the root set up to deny access to anonymous and allow access to any authenticated user. We also have a wildcard MIME mapping (.* to application/octet-stream). Enable the WebDAV web service extension in IIS. You also need to set up the web server to delegate permissions to all the file servers you may be accessing so it can pass on the user's credentials.

If you have Macintosh clients you may also need an ISAPI filter that maps 401 to 403 errors for Darwin clients. Microsoft and Apple disagree on how to handle the situation when you don't have permission to write to a directory. Apple keeps resending the credentials on a 401 (Access Denied) error, translating it to a 403 (Forbidden) error keeps this from happening. By default Apple likes to write a "dot" file to every directory it accesses. Navigating through directories where you don't have write access will end up crashing the Finder if you don't have the filter. I have source code for this if needed.

This is all off the top of my head. It's possible (probable?) that I may have missed something. Feel free to contact me via the contact information on my web site if you have problems.
