Before I get into anything else, I’d like to say that I’m releasing the TeX sources to everything but the pure content of the translations as Creative Commons BY-SA. Each bible contains a LICENSE.tex file that details the license for that particular translation/version. For example, the KJV TeX sources are public domain, but its class file (that which actually formats the content) is in fact CC-BY-SA. Thus, you are free to do whatever you will with the content of the KJV, but its layout is under Creative Commons.
Similarly, all other (future) versions will have a separate license for their content as opposed to their layout.
