As an alternative, might I suggest CloudFS? It's essentially a set of
GlusterFS translators, one of which not only limits client operations to
a specific UID/GID range but also dynamically maps between the client
and server UIDs based on the client machine's identity (which itself can
be determined in multiple ways including SSL authentication). In fact,
this translator was just merged up to the CloudFS master branch
yesterday, so now would be an excellent time for someone to try it and
provide feedback.
