The highlights are: - NFSv4 allows *nix and windows clients to play well with each other (NFSv4/CIFS clients can interact appropriately). - Strong security (authentication/integrity/privacy) is required of implementations. - A single protocol instead of a collection of protocols (e.g. file locking, ACL support are in the protocol) - Delegation (similar to CIFS oplock support) allows for more aggressive caching at the client
The University of Michigan/CITI work is the first to "release" but the other implementations are not far behind. We will be meeting at Connectathon in a couple of weeks to do interoperability testing. Should be a good event.
