I've been slowly designing an open source drum lesson book. If I had more time, I'd put more effort into it.
Currently, there are a few drum books that every drumset player works out of (Syncopation, Stick Control, etc). Most people don't play what's in the books note for note. Instead, they modify the lesson to fit whatever they want to learn. If they were available under a free license, it would be easier for teachers and other drummers to publish their own modified lessons.
I have no delusions that a free drum book could replace the classics. I'll consider it a success if it just helps my students. And who knows, it might catch on.
