I think it is just what I need. My user case is ftp server. Every customer
has own chrooted directory and the ftp server file space is under /afs

When customer log in the customers home directory looks like this:
upload      ( permissions are "li")
donwload  ( permissions are "lr)

Now customer can upload files to the upload directory and be sure
that no one else can read/over write uploaded files (even if customers
passwd is stolen). Customer don't know afs-permissions but one thing
they do is "ls -la" after uploading files and if output is something like
-????????? ? ?   ?      ?            ? uploaded_files
they think that uploading is failed.
