Content Management System - ASP, Flash

I am an interface designer (with some knowledge of ASP) needing a CMS to “plug into” the back of my static sites. Why? So clients will stop buggin’ me about text edits. The CMS (or site admin) needs to “split out” clean code (xhtml / css and possibly xml), so it can be incorporated into flash only sites and conform to web standards. The CMS would have to be easily to plug into different site with different content and navigational requirements. Of course, it would have an admin login and be located in the “/admin” directory of the site folder. I would like the CMS to include a SIMPLE WYSIWYG text editor. It would only allow users to: bold, italic, underline, created lists, create headings, and place images. It will NOT allow users to change font style, change font size, or any thing else that would alter the front-end design. Finally, the CMS code base needs to be simple. I’ve evaluated other solutions from Hotscripts, Aspin, etc. and most of the code is just bloated. I don’t need thrills, just simple and clean output and content management. Oh, did I say SIMPLE!!!!
