I've found that this actually can work. It makes an interesting use of the slide show's undocumented oninit feature, and how well the slide show is written visa vis jQuery's No Conflict mode. I would generally advise using two scripts which work off of the same script library, rather than two different script libraries. However, in this case both scripts are so robust, who can resist?
That said, all you need to do to set up a demo is to follow the instructions for Ultimate Fade...
