Dear Bruce and all
Thank you very much for taking the time to clarify this point about
the materials.
Of course, i would not expect something like "wood" to be represented
by the classic material parameters as it is done through shaders. This
is because these material parameters describe the properties of a
surface in general and are taken into account by the lighting model.
However, these are still useful since they can be used to define a
multitude of materials such as those described in the following lists:

http://www.opengl.org/resources/code/samples/sig99/advanced99/notes/node153.html
I discovered VPython only recently so i do not know what was the
situation in previous versions. But these implementation decisions are
anyway up to you.
Thanks again.
By the way, i noticed that there is probably no way for someone only
viewing the list through email to download the AC3D model loader i
posted two days ago. The code is available from the Web View or by
following this link:

I hope this helps.
All the best
