166500 desktop widget to update news

I am looking for someone who has developed this desktop type widget before or used Yahoo! Widget Engine to build the widget. currently we are looking for simple widget like this one - [login to view URL] - everyday we post news and articles to our Joomla site - we just want to push the content to the widget on people's desktops similar to rss feed type and some sort of small advertising spot. Private message me if you have this exisiting software or have done this work before since it is wide spread via the Yahoo! Widget Engine.
