That's a good idea, but doesn't work for us because we distribute the boards 
with valid MAC's in the enviornment, hence every one must be different, and 
gets hand programmed.
I don't know that there's a way to get around this, but if someone has come up 
with a tool, I would love to get my hands on it!
