Eric,
 
If you can wait for one more week or so. We will start 
Beta testing our triangulation toolkit. This MapInfo plugin will offer 
the following functionalities:
 
-    Fast Delaunay 
triangulation
-    Contour creation (both lines and 
surfaces)
-    Interpolation to MapInfo grids 
and...
-    The creation of Voronoy polygons (also 
fast :) 
 
If you want I could sign you up as a beta tester. 

Just out of curiosity... how large are the datasets for 
which you want to create Voronoy polygons?

  Hi Folks:
   
  I'm sure I used to have a tool that would create 
  voronoi polygons
  but I seem to have misplaced it!
   
  As I remember, it was very slow, but gave you an 
  option to put
  in a maximum radius---so that a store with no 
  other store within
  a few miles could just appear as a circle with 2 
  mile radius for
  instance...
   
  Any ideas?
   
  Thanks!
  Eric
