We've planned support for WebDAV, but not at a specific release. What we would like to support is simple upload of documents using WebDAV. That way you would be able to upload a bunch of word, pdf, images or other documents with drag and drop in windows. Very useful for intranets where you need to handle alot of documents in a simple way.
I just read you message Paul, Its one of things I wanted to discuss too as its vital to making the first steps for eZ as a viable Knowledge management system.
