Camping list - Jun 2008 - how to add a method without coding it directly into app?

i''m missing something here.
how would I code this outside the application to be shared with other 
Camping apps?

module Blog::Controllers
    module AuthenticationHelper
        def self.included(base)
            class << base
                define_method :authenticate do |*a|
                    a.each do |meth|
                        if method_defined?(meth.to_s)
                            alias_method "__#{meth}__", meth
                            class_def(meth) do |*a|
                                @state.Back=@env.REQUEST_URI
                                return redirect(Login) if @state.blank? 
or @state.user_id.nil?
                                send("__#{meth}__", *a)
                            end
                        end
                    end
                end
            end
        end
    end
end

any hints? thanks!

Change Blog::Controllers to Camping::Controllers and require it before  
Caming.goes :somewhere_else

..an oversight. :-)

modified slightly to work:

class_def(meth) do |*a|
    controller_module = self.class.name.split(/::/)
    controller_module.pop
    controller_module << :Login  # maybe this could be passed as an arg
too
    controller_module=controller_module.join("::").constantize
    @state.Back=@env.REQUEST_URI
    return redirect(controller_module) if @state.blank? or 
@state.user_id.nil?
    send("__#{meth}__", *a)
end

thanks for the speedy reply!
