Service Links In Caption

Is it possible to add Service Links to the caption of a Lightbox2 popup?

I have read on a post that I can't find at the moment that you can add html content to the Title of a Lightbox2 popup like so:
<a href="http://video.google.com/videoplay?docid=22349072348092348324" rel="lightvideo[groupname][<b>Caption Title</b>]">Video 1</a>

Is it possible to add php content to the title if the input format is set to a php/code type?

According to this post: http://drupal.org/node/691602

I would then need to do something like this:

<a href="http://video.google.com/videoplay?docid=22349072348092348324" rel="lightvideo[groupname][<?php if (isset($node->service_links) && (!empty($node->service_links))) {
  $item['service-links-twitter'] = $node->service_links['service-links-twitter'];
  print theme('links', $item);}?>]">Video 1</a>

Or would the best and only way be to have Lightbox2 display a node with service links attached using a Lightmodal?

Thank you.
