I believe you can get to anything:

If a request is made to a resource inside a virtual host, $srv_cfg will contain the object of the virtual host's server.
  my $srv_cfg = Apache2::Module::get_config('MyApache2::MyParameters', $s);

To reach the main server's configuration object use:
  use Apache2::Module ();
  use Apache2::ServerRec ();
  use Apache2::ServerUtil ();
  ...
  if ($s->is_virtual) {
      my $base_srv_cfg = Apache2::Module::get_config('MyApache2::MyParameters',
                                                    Apache2::ServerUtil->server);
      print $base_srv_cfg->{name};
  }

However, I think you can still get to anything you want:

  my $tree = Apache2::Directive::conftree();

by traversing this far enough down.  (see t/response/TestApache/conftree.pm)
