Oh man, now I love books. That enthusiasm is infectious!
Just reading through it, I was thinking about a big book we have that's the complete genealogy of our family going back to the 1600s. It's in fine shape now, but it's definitely something I would pay to have nicely and artistically bound, because I want it to last generations.
My gut says, if you could find a clean way to put Ancestry reports in a book, you would have a real business.
