CODA is really dead. If you want a disconnected filesystem, check out
Intermezzo, which is part of the Linux kernel as well.

I picked up a NetDisk from Fry's over the past week and attempted to get it
to work. Unfortunately, the only Linux drivers they have right now are beta,
and only for Redhat 8 & 9 at that. Their "admin" tools require Tk (not on a
server!), and appear to be some hacked up version of their own code and net-snmp.

The windows drivers worked a bit better, but would say "Drive has been
disconnected" every so often, when nothing had changed physically.

Nice (and relatively cheap) idea, but their implementation has a way to go.

It's only after you've lost everything that you're free to do anything.
