You must own the working mapset (so you can create new maps, *change the
region*, apply your own color maps to other's raster maps, etc.). Once
each user has their own working mapset, use g.mapsets to add the other
mapset to the search path so you don't need to use the "@othermapset"
notation all the time. That should be it.

I use them extensively (although mostly single user access). No problems.
