Thanks for the info... alas I specifically desire a gnuplot based 
implementation that uses octave handle graphics.  I'm in the midst of a 
large project which demands consistency between plots, I've committed to 
use the gnuplot epslatex terminal (preferably through octave).   I'll 
look into the code and see if I can contribute something that would 
work... but don't hold your breath.
