My understanding, having never actually _used_ 464xlat knowingly, is that you open a socket and send on it and it just works, and that since most applications don't try to figure out what their source address is this isn't a problem.

Well and good, but I think you missed my point, which is simply that your explanation isn't going to help the people we need to help.   If indeed there is no API extension required, that's great, but I think the base of James' request was simply to have the IETF say what needs to be done to make 464XLAT work.   Either we've already said that, and James doesn't know what document to read, or we haven't, and there's a problem we could solve.   If the document is only a page, that makes solving the problem pretty easy.
