Hrm, that looks interesting, the sql is certainly nice and simple enough, but I have to wonder, how do you maintain it? What happens if, after you've got all your nice lft and rgt columns set up, you want to insert a new node someplace?

After thinking about it for a bit, I think the biggest win is just to store 2 ids, an "ultimate parent" and a "sub parent", then I can just get all my nodes in one query and munge them in to a tree in perl.
