I think that in a UPG environment you could achieve the same (at least
in the case when there is a certain directory in which all those users
create their files, like /var/www/ or something) with a combination of
a common group, umask 072, and a setgid bit (and most likely a sticky
bit too to prevent deletions) on the shared directory.
