Slim version of Jetpack unlinked from WordPress.com :) Supercharge your self-hosted wp site even you're NOT WP.COM users.

This plugin adds support for video and audio shortcodes to posts and pages.\ If you have 'bbPress2 shortcode whitelist' installed, you can also opt to allow them in comments, bbpress 2.0 forums and buddypress activity, group forums and private messages.

This plugin is useless now. WordPress 2.5+ comes with this functionality already.
