Hello Pedro,

you may wish to read the thread
http://www.coda.cs.cmu.edu/maillists/codalist/codalist-2002/4300.html
(or you probably already did)

the most evident issues are
- Windows applications opening files read/write and causing unnecessary
  stores and possibly conflicts
- Coda conflicts are not repairable via Samba
- you need cleartext passwords and a suitable Coda pam module

It looks like an amount for at least 3 coda server processes,
each with 1G RVM.

The [samba server] client cache size depends on how big part of that data
is going to be used simultaneously/often. Let it be several gigabytes and
watch the usage. You can easily reconfigure it (though losing the cache
contents each time).

You may want to test the current native Coda client for Windows from cvs.
No idea of its status but if it works for you, it would be the right
solution compared to a samba gateway.

It should work but be warned that you will certainly have one of the
biggest existing production setups. Plan well for disaster recoveries :)
