Drupal 6 site detection

Can i suggest the following modification to the function drd_server_server_domains

This essentially just makes an educated guess at all the domains on the server if the sites.php file hasn't been created

function drd_server_server_domains($sid) {
  $user = drd_server_load_user($sid);
  if (is_string($user)) {
    return drd_server_error($user);
  }
  $sites = array();
  if (file_exists(DRUPAL_ROOT . '/sites/sites.php')) {
    include(DRUPAL_ROOT . '/sites/sites.php');
  }
  else {  	
	foreach(scandir(DRUPAL_ROOT.'/sites') as $file)	{
	  if(is_dir(DRUPAL_ROOT.'/sites/'.$file) && !in_array($file, array('.','..','default','all'))) {
		$sites[$file] = $file;
	  }
	}
  }
  
  $output = array();
  foreach ($sites as $url => $id) {
    if (isset($output[$id])) {
      $output[$id]['aliases'][] = $url;
    }
    else {
      if (file_exists(DRUPAL_ROOT . '/sites/'. $id .'/files/.htaccess')) {
        $output[$id] = array(
          'url' => $url,
          'aliases' => array(),
        );
      }
    }
  }
  return drupal_json_encode($output);
}

Maybe there could be some additional logic here.
perhaps even read some info from settings.php in each folder to figure out if there are multiple aliases to the same site.
