Manually load Jetpack modules (e.g. for dev or offline environments); drop this in your mu-plugins folder

jetpack-loader.php

<?php
// TODO: don't run if Jetpack is active

add_action( 'plugins_loaded', function() { 
	if ( ! file_exists( WP_PLUGIN_DIR . '/jetpack/' ) ) 
		return;

	$modules = array(
		'modules/contact-form.php',
		'modules/shortcodes.php',
		'modules/widgets.php',
		'modules/comments.php',
		'modules/carousel.php',
		'modules/custom-css.php',
		'modules/sharedaddy.php',
		'modules/gravatar-hovercards.php',
		'modules/minileven.php',
		'class.jetpack-user-agent.php',
	);

	foreach ( $modules as $module ) { 
		require_once( WP_PLUGIN_DIR . '/jetpack/' . $module );
	}

}, 99 );

This is pure gold, I can finally develop locally with the ShareDaddy plugin.

Is this in the VIP documentation?

EDIT: I added a condition to check if the class "Jetpack" exists, because although the Jetpack files may exist, the plugin may not be activated, and if it's not, the function above will throw a fatal error.

if ( ! file_exists( WP_PLUGIN_DIR . '/jetpack/' ) || ! class_exists( 'Jetpack' ) ) {
return;
}
