I've got 3 machines working this way under 10.5.8 server. I typically use AFP for homes. I saw the problems that you are talking about. I had to switch to using an NFS share home dirs for those users for the 3 ML workstations to work.
Just an FYI for anyone who might be searching for this solution. I recently discovered that the NSF share fix works also on a 10.6.8 OD server with OS X 10.8 clients using network homes, to resolve write to network application compatibility issues.
