All on this thread, Let me boil this down to what I consider the essence of this thread. This entire discussion on publish-Subscribe to notification of events, or the automatic enrollment in a notification event because of the user, e.g. owner, is the genesis of a workflow/lifecycle module within the WebDAV server. Am I off base here? When you peel enough layers off of this discussion, isn't workflow/lifecycle at the heart of it? Except for the simple case where a single item is modified, but even that needs to have exceptions.
