What I suggested was - emulated as shell commands as you did:
as user joe
$ cd
$ mkdir -m 0 upper_dir # upper_dir is not accessible by anyone except
owner and root; see (1) below
$ chmod 01777 upper_dir # has now rwxrwxrwt
$ cd upper_dir
$ mkdir -m 0 lower_dir # see (2) below

(1) user scott tries
$ rmdir ~joe/upper_dir
UX:rmdir: ERROR: upper_dir: Not privileged

(2) user scott tries at this time
$ rmdir ~joe/upper_dir/lower_dir
UX:rmdir: ERROR: /home/joe/upper_dir/lower_dir: Not privileged

Any more questions?
