By the way - an amazing coincidence. I recently decided that wall textures should be possible with a shader that requires no UV mapping. It may be possible to generalize.
The technique is to determine the surface normal. (Which we have in the N node). Do a cross product with the "Up" vector (Y) to get a local "Right" vector. Then generate a mapping based on the Up and Right vector space in 2D.
I built it in Poser nodes - works great. Planar shaders can be constructed with this technique so that you don't have to UV map any walls.
I'm working on roofs, too.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
