Coda is not really a network fileserver in the sense of NFS or Samba.
You cannot run Coda without a local filesystem.[1]  Furthermore, Coda
doesn't really have any concept of "read-only volumes" (it used to,
but as far as I know there never were any optimizations done for this
case---and anyway, you mention "editing").  So to preserve atomicity
of changes, Coda caches the _whole file_ locally before the open()
call returns.  Huge file => huge latency.

You probably want NFS or Samba, really.

[1]  You can host the filesystem on a ramdisk if that makes you happy.
