Why not just make all of the users part of the same group?  I checked my
FC3 system and as a non-root user, I have a umask setting of 002 which
means I create directories that are "rwx" and files that are "rw" with
respect to everyone in the same group as me.  This should work just
fine.  Even if the umask settings are currently 022 on the system in
question, they could be changed to 002 and not sacrifice much with
respect to security.
