Limitiations of Read Only maps? default map only vs multiple map s?

["Brook, Bryan S" <bryan.s.brook@LMCO.COM>]

        If you are running in a 1 map environment (default map ONLY) and you
have multiples users using this map, what will be different for the people
who have the read-only copy?  Will they still see status changes?

        It seems to me that there isnt any benefit to creating 6 maps (one
for each user) if they all are the same "view".  If you had to remove an
object, you would have to do so 6 times.  Why would you want to run in a
multiple map environment?
