Careful: Coda is experimental.  You can use it, but you must absolutely be
certain that you have good backups etc.

The tickets expire every 25hours.  A PAM module could do the job - that
shouldn't be so complicated to write (volunteers?).

You will have to tell clog to read the password from a protected file.

Auth2 can use a Kerberos password database.  Perhaps that is useful to
you, since that can give a system wide password database (which is also
quite secure).

NFS has no security so that does "help" in making it simple.

Good luck, thanks for your interest in Coda.
