H5P, an MIT licensed community driven project, is a HTML5 authoring tool which is currently integrated with Drupal, Wordpress,and Joomla.
A few individuals have integrated this with Moodle successfully but have not made their code publically available. I emailed the H5P team directly and they said it is a matter of funding. Do you have any ideas on how to get this integration happening?
