Again, I must admit, the various licensing combinations and permutations brought out by Karl, Toby, Mav, Jimbo, and others are mind-bending (for me anyway). Rather than go on about this any further, and save time/bandwidth, I would appreciate any pointers (links, etc.) to the best descriptions of the differences between open source licenses. Send me anything you deem valuable.
Also, I trust that when the pilot finally gets off the ground, that folks here will have done their level best to see that the finished books are able to be taken up by schools and used without requiring the intervention of copyright attorneys. That's the bottom line. The public education sector is laden with so much bureaucracy, and rules, that any potential problem becomes magnified - often to the point of paralysis. In sum, that's what we want to avoid; I trust the folks in the project are sensitive to that. Thanks again for your efforts, and dedication to making this project happen.
