 well, as mentioned above, open textbooks definitions usually imply that 
they can be used freely, like software licensed under the GPL (Sage is GPL 
licensed) etc. With the NC part, this then isn't an open textbook any more

The bunny picture on page 195 is NC licensed. What is the agreement between 
the copyright holder of that image and your plan regarding charging 
royalties and splitting them? That detail alone would make this book very 
proprietary, since you're now the only one with that licensing agreement 
between the copyright holder of that picture and nobody else has a real 
chance to use this book in a context like teaching (simply because it is 
hard to track down the person, etc.). I'm not sure if this is the 
intention, but I'm just mentioning this. I would like to see this book 
getting used somewhere else …

In "Any last words" on page 10 the license is referred to as

> CC-BY-SA

which is what I'm arguing for. Problem is, it is incompatible with the NC 
of the bunny picture:
