At our site we have two copies of Grass (one 4.0 the other 4.1), and
both are regularly used by up to four users. I don't know how Grass
will hold with more users than that, but I'd say it probably depends
on the machine you're running Grass on, and the OS, rather than on
Grass itself. Multiple users have to worry about one thing only, and
that is setting the correct DISPLAY so that their Grass monitor
doesn't appear on somebody else's screen...There are no problems 
with multiple use of a single mapbase, as long as you stick to the
LOCATION/MAPSET structure.
