Giorgio,

  You bet it is! That's exactly what we do here.

  GRASS is installed on salmo:/opt/grass5/ and _all_ spatial data are stored
on caddis:/usr4/. On caddis, in /etc/exports/ are the lines:

/usr2   192.168.55.0/24(rw)
/usr3	192.168.55.0/24(rw)
/usr4	192.168.55.0/24(rw)

  This means to export the /usrX file systems to the entire network (our
private, class C network) in read/write mode.

  On salmo, in /etc/fstab are the lines:

caddis:/usr2            /mnt/usr2       nfs     rw,rsize=8192,wsize=8192 0 0
caddis:/usr3            /mnt/usr3       nfs     rw,rsize=8192,wsize=8192 0 0
caddis:/usr4            /mnt/usr4       nfs     rw,rsize=8192,wsize=8192 0 0

  When I want to run GRASS to work on a project, I cd to
/mnt/usr4/projects/... (that is, the GRASS ``location" directory), then I
invoke GRASS5.

  $GISBASE is /mnt/usr4/projects/. Location could be nevada/, oregon/,
alaska/ or any other overall location for projects. And mapset would be the
specific project directory. I keep my PERMANENT files in the location, but
separate from each mapset.

  Works for me on my Red Hat 6.2 network. YMMV.
