Panels integration

I didn't see any panels integration and I need it so I'm working on it. I've ripped the code from one of the blocks and am adapting it:

$account_id = 1;

$activity = activity_get_activity($account_id, NULL, variable_get('activity_block_'. $delta, 5) + 1);
if ($count = count($activity)) {
  if ($count > variable_get('activity_block_'. $delta, 5)) {
    $more_link = theme('activity_more_link', 'activity/mine');
    array_pop($activity);
  }
  
  $activities = array();
  foreach ($activity as $item) {
    $activities[] = theme('activity', activity_token_replace($item), $item);
  }
  
  print  theme('activity_block', $activities, $more_link);
}

That seems to work fine when dumped into a page. Any issues with using that code? If not, I'll wrap it into a panels content type and feed it off the user context. Is this something you'd be interested in adding to Activity?

Thanks,
