Rails - Nov 2009 - Digest auth with Rack/Metal

Hi folks,

I''m trying to so some digest authentication in Rack via Metal. 
I''ve
found the:

  http://rack.rubyforge.org/doc/Rack/Auth/Digest/MD5.html

Class, but I don''t have a great idea of how this fits into metal.  It
seems like I should be able to do something similar to:

  class MyAuth < Rack::Auth::Digest::MD5
  
    def initialize(app, realm=nil)
      super(app, (realm or "Awesome Auth")) do |username,password|
        username == ''bob'' and password ==
''jimbo''
      end
    end
  
  end

Any thoughts or experience using Rack::Auth::Digest::MD5?  I think I
could just instantiate it on each request, but it''s built *like* a rack
application so I don''t see why that''s needed.

Thanks all,
