This is an extension to the PyWebDAV server. I've done two things. One, I've lightly integrated it with Twisted, so that it runs as a twisted application. This version doesn't make use of twisted's Deferred mechanism, as the file system interface that backends it is synchronous. To really use WebDAV with twisted and an async backend, more work must be done. Secondly, I got it to work with Windows 7's Microsoft-WebDAV-MiniRedir/6.1.7601, the thing that talks to the WebDAV server when you "Map Network Drive...".
There is no authentication, nor is there security. Easy enough to add.
