[Zope] Simple high-level question - mabye about WEBDAV?

I am looking to extend a zope portal to allow authenticated users to upload/download files... the idea being to support a shared drive containing various files available over HTTPS and available anywhere there is web-access. Ideally this notional 'web-drive' should be accessible using Windows "Web Folders" -but I'd also like for it to support ACL-style permissions with respect to file-access by other authenticated users. Are there any "products" which already address this requirement?
