Hello Samir,

Coda has been developed among other things to offer better access control
methods, based on the user authenticity. Just use acls.
(even root processes on hosts can have their own accounts, of course)

If you are going to conceal the fact that the servers are running Coda,
or really have reasons to limit the access by hosts not by accounts,
then you may have to set up firewalls or packet filtering, but it is
another story, imho.

Coda's design is very different from NFS or alike, and I am a bit
afraid you are looking in a wrong direction.

Feel free to explain the reasons that make you feel IP-number-based
restrictions are necessary for you.

My 2c,
