support sub-shares?

What if you for instance get read access to /foo but write access to /foo/bar? In OCM that would be two separate shares, and if you open /foo and then drill down to /foo/bar, the receiving server will not recognise that you entered the folder where you do have read/write

Seems right on the surface, /foo/bar is more specific than /foo. My question here is are we going to mimic POSIX file system permissions?
