Ok, we found the original engineer who bought the stuff... he has dim memories 
of using it as a long high voltage probe hooked to a plate capacitively coupled 
to a transmission line tower to measure lightning induced voltages.  The 
distributed resistance apparently would work better than a lumped resistor 
because of the small capacitance of the plate probe... and would damp transient 
reflections.  Apparently this was derived from a paper that described how to 
measure voltages in a computer when you needed probes that would reach around 
the room that the computer filled.
