> Correct me if I'm wrong, but I believe "Jive" is equivalent to a very basic form of Ebonics (at least the African-American slang, if not the whole complex inverted grammar structure or whatever that Ebonics is supposed to encompass).

You're right. I tend to think of "jive" as being the variation spoken in the 1970s, though, whereas "ebonics" seems to be the variation spoken today. At least I hope that's an accurate distinction, because the dialect is intended to emulate 1970s speech, not today's.
