After my day of searching about this topic, I found that using the multipart/mixed content type involves a server push (as opposed to the usual client pull). This functionality is not supported in Internet Explorer. There is some example code being used in Netscape 4.X browsers and email but nothing else.
Hopefully someone can prove me wrong and find a way this can be done, but for now I've given up for more productive work. Thanks for the information.
