Generating Views Block to list Taxonomy Terms of nodes curently visible in a Views Page
Offhand i'm not sure how Context will help you do this ... off the top of my head this solution came to mind.


In your 1st view make the Tag field a hidden field the view so the View knows about it.
Use hook_views_pre_render to loop through the results (and maybe respect page offset and # of items per page -- you can get that from the $view object) and grab your view field Tag values and store them into an array.
Still in hook_views_pre_render you can set $view-&gt;attachment_after = $some_string; where $some_string is like the list of your Tags.


In code it will look something like this:

function MYMODULE_views_pre_render(&amp;$view) {
  if ($view-&gt;current_display == 'VIEW_ID') {
    $tags_on_page = array();
    // $_GET['page'] has page number.
    // $views-&gt;items_per_page has items per page count.

    $page_offset = intval($_GET['page']);
    // this is somewhat wasteful, but easier than a loop at the moment.
    $paged_results = array_chunk($view-&gt;result, $view-&gt;items_per_page, TRUE);

    // Build up the Tag list for X page of the results.
    foreach ($paged_results[$page_offset] as $i =&gt; $result) {
      $tags_on_page[] = $result-&gt;value; // save the taxonomy term name to the tags list.
    }

    // Take our tags and build a block of HTML to embed after the view.
    // Alternatively, maybe take these tag values and pass them as parameters
    // to a new view we attach after programmatically -- thats more work.

    // if you know the url prefix you've given these taxonomy terms use it here, or use something like entity_uri().
    $num_tags = count($tags_on_page);
    if ($num_tags) {
      for ($i=0;$i&lt;$num_tags; $i++) {
        $term = $tags_on_page[$i];
        $tags_on_page[$i] = l($term, '/URL/ALIAS/BASE/PATH/TO/TERM' . $term);
        // or, ... $term may have a path value already ... I cant remember :).
        // $term = taxonomy_get_term_by_name($tags_on_page[$i]);
        // $term_path = entity_uri('taxonomy_term', $term[0]);
        // $tags_on_page[$i] = l($term[0]-&gt;name, $term_path);
      }
      $links = implode('&lt;br&gt;', $tags_on_page);
      $view-&gt;attachment_after = '&lt;div class="myBlockAfterView"&gt;&lt;h3&gt;Related Tags&lt;/h3&gt;' . $links . '&lt;/div&gt;';
    }

  }
}
