Konstantin describes a node hierarchy system powered by nested sets. Thats far more powerful than Ber's relations as described in those links. Nested sets allow you to express complex hierarchies with excellent performance. Thats not true with flat relations table.
Many of us in Amsterdam discussed nested sets as a promising solution to our widespread neet for hierarchy. I encourage Konstantin and others to pursue this solution. Book.module is also excellent test case IMO.
Let me point out that Allie's hier module wants to use nested sets. See http://donorge.org/d_items/view/331 and http://cvs.drupal.org/viewcvs/drupal/contributions/sandbox/vauxia/hier/READM... Regards NK
