Introducing Pivot.js - A brief introduction to a new reporting library

Wow! This could make work so much fun!

I read the license (see https://github.com/rjackson/pivot.js/blob/master/LICENSE), but I'm not a lawyer. Would someone who is using this to write reports for their boss at work have to implement it all over again? Does that count as commercial use? (What is your relationship with ProMedical?)
