Basic knowledge (and use) of Blender: This shader requires all meshes it's used with to have been exported using a custom SolidWire export script (provided in /dist/io_export_solidwire_fbx.zip).
For an overview and in-depth guide on working with SolidWire, please check out the wiki.
A special thanks goes out to the friendly people of Unity's forums for helping me out when getting this project started.
