Come on guys!  What do you think group IDs are for?  A simple solution
to all this is to make the 'chgrp' program usable by mere mortals as
long as they are allowed to 'newgrp' to the specified group, and as
long as they own the original files.  (We have already done this here
at U of MuD.)  Then you write a shell script (or program, if you want
some speed) that lets a user create a new group in the /etc/group file,
with himself and specified others on it.  Now, for two people to work
together on something, they make up their own group, chgrp and chmod any
existing files, and voila! no security problems.
