Wordpress Widgetizer

I had been meaning to build a widgetizer - something that could widgetize any plugin for Wordpress. But Erik Rasmussen has beaten me to it (via Blogging Pro). It might look like just another text widget, but it executes the PHP code typed within it. Wordpress introduced widgets in its recent versions, but not all plugins were widgetized creating problems for users. I had widgetized the Random Quote plugin and wanted to widgetize some more. The difference between what I had thought and this widgetizer is that this will not be able to customize plugin options through the widget GUI. I wonder if this can be built on it!
