Sorry, this version is way past support end of life.

File system perms is of course the lowest level to control who/what can 
do what, so using them properly should work for what you're wanting to 
do, BUT...

Please upgrade to latest release/stable version - or even the newer1.1, 
which is at RC stage now...
