Embedding screencast.com Videos in WordPress Multisite

Question

I've got a multisite installation of WP 3.5.1 running, and I'd like to for users to be able to embed screencast.com videos into posts, preferably with a shortcode like you do with YouTube or Vimeo.

I can do this using the full embed code from the screencast.com sharing menu, but I can only do this as a super admin. All other users have and tags stripped out of their posts. I can get around this by installing the Unfiltered MU plugin, but that's not ideal, since it allows users to put all sorts of untrusted code/tags in their posts.

I've searched pretty extensively for some sort of simple plugin, and have come across this Screencast.com Video Embedder that seems idea, but it hasn't been updated in 2 years.

So I'm wondering if there are any other solutions that might work for this.
