Unless you already have a CODA/Kerberos setup to tie into, or need the
ability to work disconnected or some other CODA-specific feature, I'd
consider SFS (http://www.fs.net/) -- no new filesystems or databases
required, works like NFS, but without portmap listening on an external
interface. Portmap *does* listen on localhost on the SFS server, but
I plan on using it for file services to clients outside my local
subnet. At least when I tested it, the speed wasn't great (2MB/s on a
100Mbit network, compared to 8MB/s with regular NFS on the same
network and same sufficiently powerful machines), but that may have
been a local configuration problem, fixed in more recent versions, or
irrelevant to your situation.
Woody and Sid should both have SFS packages already made, but those
packages ported back to Potato with minimal effort several months ago.
