I would like to point out that the proposal for NFSv4's first minor
version contains a directory delegation feature. Within that is a
notification mechanism. The client is able to ask for asynchronous
notifications on a directory (and the objects within it) for
various events. Those events include things like:
adding a file
removing a file
renameing a file
attribute changes (for directory and objects within it)
cookie verifier change (really an NFSv4 thing)
The scope of a notification is just the directory and objects contained
within it (not further down the tree).
As mentioned, the events are asynchronous in the sense that the server
will not delay operations just because it needs to notify a client
of one of the above events. The client gets to ask for time granularity
of the notifications. The server is not obliged to provide
notifications (not supported or too many requests, etc.).
Thought this would be helpful information for the discussion.
