I just thought that it would be nice for plugin developers to be able to embed their plugin pages on wordpress.org/extend/plugins. Something like this shouldn't be too hard anyways:
Imagine the image above as an iFrame with a stretchy background. Plugin developers can promote their plugins on their own websites by just putting this iFrame on their pages so they don't have to put giant buttons for download or upload the plugin to their own FTPs.
What do you say, Automattic? :)
