You can try this:

$res = $vbulletin->db->query_read_slave("SELECT subscribethread.userid, username, usergroupid, infractiongroupid, displaygroupid FROM " . TABLE_PREFIX . "subscribethread AS subscribethread 
                                         LEFT JOIN " . TABLE_PREFIX . "user AS user ON(subscribethread.userid = user.userid)
                                         WHERE threadid = $thread[threadid]");
$subscribed_count = 0;                                         
$subscribers = array();
while ($row = $db->fetch_array($res))
{
    $subscribed_count++;
    fetch_musername($row);
    $row['is_last'] = ($subscribed_count == $db->num_rows($res));
    $subscribers[] = $row;
}
vB_Template::preRegister('SHOWTHREAD', array('subscribed_count' => $subscribed_count, 'subscribers' => $subscribers));

and in the SHOWTHREAD template:

</BR>{vb:raw subscribed_count} subscribed to this thread</BR>
<vb:each from="subscribers" value="subscriber">
<a class="username" href="{vb:link member, {vb:raw subscriber}}">{vb:raw subscriber.musername}</a><vb:if condition="!$subscriber[is_last]">, </vb:if>
</vb:each>

And I know it doesn't give you colored user names or show you which ones are logged in or are friends. If you really want any of that I'll have to work on it a little later.

Edit: Well, now it does color the username, which turned out to be pretty easy. I think that matches what's in the other lists in the info, so I probably won't add anything else unless someone really wants it.
