Great!  Do I understand that you would deliver mail into Coda volumes on
one client and let other clients access the mail from their desktop Coda

You may want to tell me in detail, since there might be gotchas, which I'd
love to fix for you. For example how is qmail to be authenticated to
deliver into user files?   Also Coda ACLs are per directory, not per file,
how are you protecting your mailboxes?

Use 2.1.96 kernels an onwards.  Coda on 2.0.32 is not mature enough but on
2.1 it should work.  The inode number problems are largely gone -- I
haven't seen a problem for a long time.

I think the FreeBSD port if pretty young and we are stil ironing out some
issues.  Try Linux.

I think the kernel code is reasonably precise now and I wouldn't expect
too many problems.

We are not quite there yet. Of course that would be great.
