Zend - registering multiple namespaces...'modules'

Question

I have since drastically edited this question as I have found a solution, but not one I'm happy with. Can anybody reduce the following code:

$Loader = new Zend_Application_Module_Autoloader(
  array(
      'namespace' => 'Default',
      'basePath'  => APPLICATION_PATH.'/modules/default',
  )
);


$Loader = new Zend_Application_Module_Autoloader(
  array(
      'namespace' => 'UserAdmin',
      'basePath'  => APPLICATION_PATH.'/modules/useradmin',
  )
); 

Thanks!
