Well, whatever you guys are doing, sure looks intense!  I just browsed through this thread to its end, skipping over most of the code parts. 
What a great idea, and I'll be watching to see if you get your script running in the reverse as you seem to be working on.  I don't know how to write python code.  I just used this feature a couple of weeks ago for the first time after purchasing one of  philc's bundle!  So I ventured into this forum to see if there was something else someone was cooking up that I could give a try.

Good to see svdl and nruddock in here.  I'm already fond of them both.
