You'll have to try.  Bulk transfers are pretty good, small transactions
are a bit slow at the moment.

You could run NFS on two Coda clients  - but with a lot of write traffic
you might see a performance problem.

Yes if Unix = Linux or NetBSD or FreeBSD or Win9x.  But you will need
one server.

I recommend you give it a try!
