Widget Wrangler Plugin
Widget Wrangler is a plugin for Wordpress that gives admin a clean interface for managing widgets on a page by page basis.
It's basically Drupal Blocks on every page, with the ability to set the default location of the widgets in specific sidebars.
Widget Wrangler provides widgets as a post type, and gives you the ability to clone existing wordpress widgets.
Now with multiple 'sidebars' (groups of widgets, drupal: regions)!
