I have gone this same route to handle common groups with my RH linux
install.  One thing I've found -- and I think is more endemic to the
Unix group system than to RH's user private group scheme in specific --
is that for a common directory like /usr/local/develop, you have to set
the setgid bit on the directory (chmod g+s /usr/local/develop) in
addition to setting the group on the directory if you want files that
are created in that directory to have the same group permissions as the
directory rather than the primary group of the user creating the file.
