Well, you don't let it allow writing from just any remote client, only the
ones that need it (yes, I know, someone could spoof the address, but chances
of that happening on a private LAN are minimal). And I think there's a
significant enough difference between r/w for one user and r/w for all users
that restrictions are a good thing. I'm not trying to argue that NFS is
secure by any means, but there are things you can do that help prevent
mishaps like your wife accidentally deleting something (not that I let her
connect by anything other than Samba though).

Definitely. NFS was concocted in a kinder, gentler time. But its really easy
to set up, and really fast. Samba is probably the best choice for a balance
of security and ease. Personally, I intend to start playing with GFS soon...
