I have not played with those products but I have examined them and believe that Sharepoint uses an ISAPI filter to re-route the webdav requests to and from IIS to it's virtual file system. That's basically what I wanted to do. But I suppose if we could build a webdav server with APACHE that would work equally well as long as it ran on Win2k and 2003. I don't necessarily need to run it through IIS if I ship my own web server to do this function. The only issue will be programmatically configuring it so that I can run them both on port 80 on the same box, but with different host headers. I will check out the apache resources.
