Yes it will texture anything. The idea of the process and RobAs script was to auto rotate a direction sensitive texture to match sloping 3D height maps. So you can have tiles, slates, planks, thatch and anything like that. If you can think of a similar application not for house roofs then it might be able to do that too - like say edge of lakes with a reed bed or palisade of spikes surrounding villages etc. I did some wood tile roof textures as a demo somewhere but I cant find them in the thread now. Maybe I deleted the images or something from FTP but I still have them locally.
edit: there, added the texture for logs/planks and a couple of others I used as well. With gimp and robs script it should be able to run it.
