I found a single open source HTML5 sticky footer player out there with an MIT license.
This could possibly be improved upon. All the other HTML5 players I’ve found so far are not open source and are for sale on various sites like Code Canyon or through their developers own websites. I’m thinking that this player could potentially be the basis for both WordPress and Drupal players, given that it’s open source on the MIT license and can be adapted for both with attribution if the license provides for that. I’m not an expert here so it’s just a suggestion, but one possibly worth looking into.
