The DAZ .exe is a complete installer, which has plus and minus points. It's something distinct from an advertisement. It's good, and it's flexible enough that you can work around some problems, but it still has problems with the readme option at the end, if you don't have IE as default browser. I wonder how filesize compares with something like Macromedia Flash. An executable would allow you to put in some sort of nominal age-lock; does anything else? Also look at the MPEG-based VCD and SVCD formats. They allow slideshows, both good resolution still images and fancy image changes at lower resolution. I don't think there's a practical work-around for the nudity rules here, and not every merchant would want the hassle of creating a promotional "video", but the concept has some value.
