Is there a NFS alternative?

[Daniel Yek <dyek real com>]

Hi,

It was a while ago when I read that NFS was difficult to secure with (the 
use of) ssh and iptables (or something like that).

I really needed an alternative that works and can be made secure. Is GFS a 
suitable replacement for NFS? If not, what is the closest thing to NFS?

Thanks.
