Helena,

I work on a small network of desktop computers, with grass installed on
one of the desktops.  It's on the only desktop situated to provide for
external access through the firewall.  I need all of the members of my
workgroup to have simultaneous access to in-progress work.

I created a grass super-user named "gis" and a group also named gis.  I
installed the grass data base as /home/gis/grassdata and modified the
security system in grass so that access to the data base was controlled by
membership in the gis group.  Further, I changed the locking system so
that multiple users were allowed simultaneous access to the same location.
Simultaneous access to the same mapset awaits changes in the way that
grass handles some settings--current region, for example.

My modifications haven't been extensively tested and I know of at least
one problem, but otherwise they work pretty well.
