What am I missing here on the transparency issue?   I am thinking
basic Color4  with the alpha value component set to 1 by default
but with the ability to override the default and toggle on the appropriate
glEnables.  Do I not understand something basic about how VPython does
OpenGL or are you referring to a more sophisticated transparency
implementation?

In which case I would argue for a simple half-way implementation at least as a

temporary  
alternative to full opaqueness, all the time.
