Rails - Oct 2005 - Privileging System / ActionController Module Question

I''m trying to write a privileging system in Rails and
getting confused with the usage of Module.

Here''s what I want:

#file app/controllers/application.rb
class ApplicationController < ActionController::Base
  include PrivilegeSystem
  before_filter :check_privilege
end

#file lib/privilege_system.rb
module PrivilegeSystem
 def check_privilege
   @session[''privileges''].each do |priv|
     return true if ???.include?(priv)
   end
   redirect_to(:controller => ''error'',
               :action=>''exceeded'')
 end
end

#file app/controllers/some_controller.rb
class SomeController < ApplicationController
  privilege_level :hello     => [:read, :write],
                  :some_form => [:write]

  def hello
  end

  def some_form
  end
end
-----------------------------------

The problem is where to put the privilege_level
routine and then once I''ve got one, where to store the
data so it can be retrieved at the ??? above.

I tried the following (in both environments.rb and
privilege_system.rb):

module ActionController
  module Dependencies
    module ClassMethods
      def privilege_level(privs)
        @@access = privs
      end
      def get_access_level(action)
        @@access || {})[action.to_sym]
      end
    end
  end
end

The data just goes off into the ether. I tried
breakpointing but can''t make any sense of where it''s
at when it''s called.

Help me OB1 Kenobi...
