cool script, but no offense or anything, but dont you  think its just more worth your while to program the script to act on models created nativly in blender, just as an easier way to do facial morphs?  say for example, you define a closed loop as the mouth and another for eyebrows and so on, you could program your script to act apon thoes.  i think that would be much more original and much cooler.  

personaly,  it is my oppinion that blender has a unique degree of creativity from its users.  in other applications, this has been corrupted due poser's almost plajoristic ease of use.  Due to poser, i am seeing fewer and fewer artists with knowledge of how to author desent materials, little knowlege of render process, and even less knoledge of modeling and topology.  Poser has virtualy no commercial use compared other applications.  I find that the most satisfying work of art is one created on one's own and when that work of art is guilt free.
