Dynamic Text That A User Can Edit

I have created a simple Flash object that presents some text; it's a rotation of testimonials. The client wants to be able to edit/add to the items. He's going to maintain the site once it's handed off through the use of Dreamweaver; I've used templates to lock down the sensitive areas, and as it's a CSS based design there are many.

Is there a way to get rotation of text without having to create the media to do it? I've tried to explain that when a page loads, it's loaded -- it's the media's job to play the pretty things. He says someone told him this would be a piece of cake in various content management softwares, but I'm convinced they meant he could edit one area of text as often as he wanted to add/change the text; not that when you loaded the page you could sit there and it would display, sequentially, N number of text bits while you sat there and watched. But I'm asking, because I'm not a genius here, and maybe there's some way to fit this bill that I'm not thinking of.
