Interesting... I'm digging into this because I'd like to record a few games by hand (which I do anyway to analyze the moves) and release them under a #freeculture license. From everything I've read so far, if I copy the moves and then add my own commentary, I can do that. I'll dig a little further. I wish I could to the same for tsumego but that's just not possible, I think (unless I'm developing my own and I don't think I'm that capable).
