Ask HN: Does iBooks, Kindle, Nook, etc offer analytics

On my drive home, this question popped in my mind and after a little GoogleFu I was unable to find an answer. So do they offer any analytics. I suspect as an author/publisher it would be great to know how many people actually read the book, where they drop out, where they bookmark, if they read it multiple times, etc. I think the textbook market could benefit from this as well
