I suggest that you investigate the NFS mount options of "hard", "soft",
and interuptable ("intr").  It is true that a hard NFS mount will hang
the processes attempting to access a down server but by mounting them
soft they will eventually time out.  Mounting via "intr" is probably
more appropriate as it allows the user to decide whether to wait for
the server to come back or interupt and try again later.

Most people who use NFS for reading news export it read-only and still
use NNTP for posting.  It is only recent versions of C news that have
the potential for putting postings in a directory to be processed later.
(And that was not for NFS but to simplify some portability/permissions
issues.)

Speaking of security, a while back the issue of NFS vs. NNTP came up and
one site described their setup using NFS and how they could never
support the same load using NNTP.  I followed their directions and, sure
enough, was able to NFS mount their news partition, via the internet!

I wonder how many sites out there have news and other partitions
mountable from outside their institution.  I suggest sites configure
their routers to block RPC on external lines.  (And rlogin, rsh, etc.)
