I'd like subscribers to my site's RSS feed to be able to receive the body of my nodes, if they so choose, and not just the description (teaser).

For now, I've hacked the node.module to output the node->body onto the RSS feed instead of node->teaser. But I'd rather let subscribes choose to between receiving the entire node or just the teaser. So, I'd like to set my site up to generate two different feeds, one that just provides node descriptions and the other with the node's body.

Is there an easy way to get Drupal to generate this feed for me without resorting to a massive hack?
