The easiest way to use this material is make ribbons of quads (e.g. by repeatedly extruding a single edge of a plane) and then giving the faces of this object all the same UW coordinates and using the UV coordinates as input to this barbedwire texture.
You can do this by selecting all faces in editmode, select the unwrap menu (U)
and choosing 'reset'. It might be neccessary to rotate all faces by 90 degrees. This can be accomplished by selecting all faces and pressing R in de UV/ImageEditor window, followed by 90
Note that this is a transparent texture node. In order to see the shadows it casts on other objects, don't forget to enable 'TraShadow' in the Shaders tab of the material window for all materials of the RECEIVING object.
Alpha (transparency) values generated this way by nodes were incorrectly calculated (not only voor Pynodes) but since revision 16104 (and therefore probably in version 2.47 final) this is fixed.
