As for using cgroup as !root user, I would advise not doing that. Again, we're moving toward a unified cgroup hierarchy. You wouldn't be creating multiple cgroup hierarchies and assigning different user accesses to them. Also, I would strongly discourage chowning sub directories in cgroupfs and letting non-priviledged users modify them directly.
