Ship_manifesto, a fannish Livejournal community dedicated to character pairings, has an essay up on Han & Leia. It features an explanation of the ‘ship (like we wouldn’t know! ;) and fan fiction recomendations. As far as I can tell this is the only Star Wars pairing currently featured, although Qui-Gon/Obi-Wan, Han/Luke, and Face Loran/Tom Phanan (!!) are in the queue.
