Themes example
-------------------
You might want to group your terms by vocab on the node display.
Here is a snippit from groups.drupal.org for node.tpl.php which does so:

<?php if ($links || $terms) { ?>
<div class="links">
   <div class="left">
    <?php if ($terms  && !$is_preview) { ?>
       <?php
        // Group terms by vocab.
        foreach ($node->taxonomy as $tid => $term) {
            $vocabs[$term->vid][$term->tid] = l($term->name, "taxonomy/term/$tid");
          }
          krsort($vocabs);

          // Render a line for each vocab. performs a query to get vocab name.
          foreach ($vocabs as $vid => $vocab) {
              $fullvocab = taxonomy_get_vocabulary($vid);
              $output .= "<div id=\"node-vocab-$vid\">". $fullvocab->name. ': '. theme('links', $vocab). "</div>";
            }
         ?>
       <div class="terms"><?php print $output; ?></div>
    <?php } ?>
   </div>
   <?php if ($links) { ?>
     <div class="right">» <?php print $links?></div>
   <?php } ?>&nbsp;
</div>
<?php }; ?>
