    Hi,
    I think you are right but nevertheless customers often require to be 
compliant IPV6
    in their system even they don't use IPV6. Soon, IPV6 deployed, NFS 
will be
    one of the first applications used. Some others UNIX systems also 
have it,
    so interoperabity it would be good Linux have it.
    But that is true it will be interested to know when and who on the 
nfs lists is interested in
    to use it.

     After a first rejected solution and some new discussion on the 
NFSV4 mailing list,
Bull (Aurélien) supplied a new document described the current 
implementation. This little design document is still here: 
http://nfsv4.bullopensource.org/doc/nfs_ipv6.php

 Any new remarks are welcome.

  What would be the mailing lists to call them to review?

     May be some on this nfs mailing list have this kind of environmments.
     What  Bull can do is to run the robustness tests we are doing for 
IPV4 on IPV6.
