I Want to Create a View that Dynamically Displays All Nodes of the Child Terms of the Current Node's Term

I want to create a view that dynamically displays all nodes of the child terms of the current node's term. I can create a view that does this for any vocabulary term I select--but I want it the view contents to be generated dynamically for the current page--whatever page that might be.

Does that sound obtuse?

Let me give an example: Let's say I have a hierarchical vocabulary of places; I am currently at the "United States" page, which, not surprisingly, has a taxonomy term of "United States" associated with it.

The "United States" term has child terms which are the states such as "Alabama", "Alaska" .... "Wyoming"

If the page I am on that has the term "United States" as a taxonomy term applied to it, I want to create a list of all nodes that have one of these "child" taxonomy terms applied to it. (Each node would have only one term from this vocabulary applied to it.)

The view that I created that does this statically exports the following:

  $view = new stdClass();
  $view->name = 'us_child_node_view';
  $view->description = 'This Is Test of Chile Node Views';
  $view->access = array (
  0 => '1',
  1 => '2',
  );
  $view->view_args_php = '';
  $view->block = TRUE;
  $view->block_title = '';
  $view->block_header = '';
  $view->block_header_format = '1';
  $view->block_footer = '';
  $view->block_footer_format = '1';
  $view->block_empty = '';
  $view->block_empty_format = '1';
  $view->block_type = 'list';
  $view->nodes_per_block = '999';
  $view->block_more = FALSE;
  $view->block_use_page_header = FALSE;
  $view->block_use_page_footer = FALSE;
  $view->block_use_page_empty = FALSE;
  $view->sort = array (
  );
  $view->argument = array (
    array (
      'type' => 'taxid',
      'argdefault' => '2',
      'title' => '',
      'options' => '',
      'wildcard' => '',
      'wildcard_substitution' => '',
    ),
  );
  $view->field = array (
    array (
      'tablename' => 'node',
      'field' => 'title',
      'label' => '',
      'handler' => 'views_handler_field_nodelink',
      'defaultsort' => 'ASC',
      'options' => 'link',
    ),
  );
  $view->filter = array (
    array (
      'tablename' => 'node',
      'field' => 'status',
      'operator' => '=',
      'options' => '',
      'value' => '1',
    ),
    array (
      'tablename' => 'node',
      'field' => 'type',
      'operator' => 'OR',
      'options' => '',
      'value' => array (
        0 => 'story',
      ),
    ),
    array (
      'tablename' => 'term_node',
      'field' => 'tid',
      'operator' => 'OR',
      'options' => '1',
      'value' => array (
        0 => '11',
      ),
    ),
    array (
      'tablename' => 'term_node_1',
      'field' => 'tid',
      'operator' => 'NOR',
      'options' => '0',
      'value' => array (
        0 => '11',
      ),
    ),
  );
  $view->exposed_filter = array (
  );
  $view->requires = array(node, term_node, term_node_1);
  $views[$view->name] = $view;

If you notice, the view filter has two filters that are applied for taxonomy terms: one is to include the children, one is to exclude the present term's node (

    array (
      'tablename' => 'term_node',
      'field' => 'tid',
      'operator' => 'OR',
      'options' => '1',
      'value' => array (
         0 => '11',
       ),
    ),
    array (
      'tablename' => 'term_node_1',
      'field' => 'tid',
      'operator' => 'NOR',
      'options' => '0',
      'value' => array (
        0 => '11',
      ),
    ),

Where the '11' is the termID for United States.

SO, how do I create a filter that dynamically inserts the Term ID into the filter?

The post http://drupal.org/node/70145#comment-204051 seems pretty close to doing what I want (filtering dynamically, but with dates instead of Term ID).

I am new to views and I just can't seem to figure out the Argument Handling Code that would create the filter I need.

Or.... am I just barking up the wrong tree altogether? (Pardon the bad hierarchical taxonomy pun!)
