Thanks guys. I don't have a strong use case but it did seem something of an oddity/incompleteness when I was implementing the eclipse plug-in to dynamically respond to znode changes. Without a Watcher available, it means that ACL changes are the one instance where a user has to manually click "Refresh" to see the latest version.
This is clearly a UI-centric example, but I am not aware of any *normal* use cases where this would be an issue.
