Add the node id of a feed item's source to the meme and related content objects

My memetracker has about 40 sources in it.

Items from some of these sources are themed differently due the information being different.

In order to theme them differently, I have to run a test against the node ID of each item's parent feed.

There does not appear to be any easy, resource-cheap way to do this.

Right now I have to run a node_load for each meme

$node = node_load($meme->headline->int_id);

Then do some funky php judo that someone on IRC had to show me after 20 minutes of begging to get $val, which is the node ID of the parent feed for the top node in a meme.

  list(, $val)= each($node->feedapi_node->feed_nids);

And I have to repeat this for each related content item.

These node_loads add up pretty quickly. If I could get the source feed's ID as part of the $meme object and part of the $related_content object, I'd be able to save some memory and improve performance.....which is pretty terrible at the moment.
