I think the 'group owner' is the one you are looking for. Besides chgrp allowed
for regular users, I still think the group-owner-thing rocks and it should be
there. (I actually just read about 'group owners' once, loved the idea, and
expected the tools to exist.. they don't? :(( )

I don't think that is a solution - but a nice workarround ;)
(Not to think about explaining two pupils, office clerks, $whatever for the
millionth time how that actually works)

I think creating a real interface instead of making the users use 'tricks' is
simply the right thing. At least to a certain degree.
Yes I agree, that 'degree' may be something different to you ;)
If that does not satisfy you:
Maybe that sounds stupid, but what is a 'technical' argument then?

great. :)

Sorry, one last thing: There must be an intermediet step that I miss, why
create new groups (is that a DoS? Create new groups in a for-loop, named pretty
much the same, to make maintaince-time extra expensive?)?
