I know what article you are talking about. It was on some site where they were using Rivendell as a business case study. Where Grant using his Reader created a demand for his product and it now took two years to get a custom frame.

I believe your stats are off though. I think it is more like from 100 frames to a few thousand per year and $6 million in sales (probably less). It looks as though that article has been taken off as I can no longer find it either.
