I have only tested it with toy hacks, because my module-ified bible script makes PHP timeout when it's adding the database. But it looks at least workable. It really wasn't much code, only about 25 lines plus the comments.
edit: *that is, provides modules the ability to add text-modification functions, not that provides the Bible lookup stuff.
