UPDATE: Sandbox module available here: https://drupal.org/sandbox/firecannon/2196695, feedback appreciated
I recently demoed the Display Suite Inception module at the DrupalSouth 2014 conference in Wellington, New Zealand and was pleasantly surprised by the positive response.
This screencast covers the module in a little more detail. This module is for creation of flexible pages by implementing a drag and drop interface on top of Display Suite. I'm aiming to have this open-sourced and on Drupal.org before the end of February.
