Well, I got the plugin. :-)

Here is a quick test. Both images use a plane primitive lit with two lights, a blue on the left and a red on the right. The top image uses a bump map (made in C3 using distance G-Buffer) tiled across the surface, the bottom image a normal map (made in C3 using Deeper) and applied to the bump channel.

No vertices are displaced so the plane edges are still absolutely square for both methods but the advantages of normal maps over bump maps are clear, I think.
