[In the picture I posted you can clearly see that all faces of the, granted, simple mesh near the light object are in fact illuminated, and those no where near it are not. I think it is a better way to achieve a torch effect than just using a DirectX light.]Yeah only the mesh near the light object is illuminated, because that's the only mesh which has the normal map applied to it. If you applied the normal map over all the geometry (like you should if you were lighting a map with a torch), the map will be illuminated in the same way as with a standard light.
But there are other really cool effect that you can achieve with this technique. You can illuminate objects giving the same effect than in Zelda: Wind Waker.
