As an aside, note that this limitation is a facet of our existing NFSv4 implementation, and not anything to do with the NFSv4 protocol itself. This functionality, the ability to transparently cross server filesystem boundaries (known as mirror-mounts), *is* supported by the NFSv4 protocol (i.e. NFSv4.0). I have basic support for this working, and once it's cleaned up and extended a little, will hope to be putting it back into our Nevada NFS client later this year. cheers, calum.
