PEP1 how-to textbook?

I know Paul probably wants to keep PEP1 free. But could selling a how to guide type text book be a small income stream? The task list and "certification" could still be available for free, but I think a how to field guide/encyclopedia used in conjunction with the big black book could still be very useful but not absolutely necessary. For example: using a hand plane or properly harvesting grain with a sythe.

I think this is a great idea. The only thing is that what you described is pretty much the next phase of this project. Except that instead of one book, lots of individual tasks will have their own thread that everyone can participate in.

For example, I'll probably be making a thread in the future about how to make a mallet. And it'll have a picture of a couple of different mallets and a couple of youtube videos of people making mallets in different ways, and details of how long it took me to make one. And the idea is that lots of people will add to that forum their ideas on how to best make one, and videos they upload of themselves making one, and so on.

And then we'll have another one for growing 50 pounds of tomatoes, and one for making a pole-lathe, and for making a 12 foot hugelkulture bed, and so on...

I still think there could be a market for an ebook, but I'm guessing it would have to be really written in a really unique perspective, or be way above and beyond the level of detail someone could get here on the forums already.
