Robin's solution may work. I have never tried it. What I have done is to
use the perms as follows:

First you decide on your "base" perms. The default are like:

  var $permissions = array(
                            "user" => 1,
                            "author" => 2,
                            "editor" => 4,
                            "supervisor" => 8,
                            "admin" => 16
                          );
I believe the design was to use binary math to produce the perms, so if we
wanted the admin to also have the user perm we would add 16 + 1 and assign
17 to admin. Let's say you want the admin to be able to do all roles then
you would add 16+8+4+2+1 to get 31. Now I say want the author and editor
role to be user, I would assign 5 to editor and 3 to author and if
supervisor was all the below then 8+4+2+1=15. Now we go back to the perms
subclass and define permissions this way:

  var $permissions = array(
                            "user" => 1,
                            "author" => 3,
                            "editor" => 5,
                            "supervisor" => 15,
                            "admin" => 31
                          );

This will do what you want...
