Hej,
It could be great if you add multisite support to this plugin.
Today in a multisite this plugin works just for the superadmin.
For blog admins the iframe is stripped before the iframe is encoded to shortcode.
This could be a great solution for embedding google maps in a multisite.(just like on wordpress.com)
