Naturally the authors did a great job is spelling out what was allowed, I hadn't noticed it 
before, sorry for the noise! :)  

"You may not commercialise this work, except with the expressed permission of the au- thors. To be clear, by commercialisation we mean that you may not sell for profit, create commercial derivative works (e.g. selling content for use as articles in a magazine). The exception to this is if all the profits are given to the QGIS project. You may (and we encourage you to do so) use this work as a text book when conducting training courses, even if the course itself is commercial in nature. In other words, you are welcome to make money by running a training course that uses this work as a text book, but you may not profit off the sales of the book itself - all such profits should be contributed back to QGIS."
