I would hope that any such scheme would also include support for
efficiently allocating very small files -- perhaps ones as small as 50

I believe that there's already a posix spec on how to do acls.  It's
not exactly pretty; most of this ugliness derives from the interaction
between chmod/chgrp/chown and acls.
