Very nice.
I wondered whether you might add the option to send in XML directly (as a long string in the flashvars) as well as with an external XML file.
I've done this with Flash components of my own, and it allows me to, say, pick items out of a database and feed them to the Flash item directly from the PHP script that builds the page. This makes life a bit easier, and is more flexible- i.e. you can match page text with Flash content. It will also lower the overhead for dynamically built pages if it's all in one script.
The other major advantage is that it's easy to gracefully degrade to, say, the first slideshow item as an img for people who don't have the right version of Flash installed.
Keep up the good work :)
