We have a new project where the client wants to integrate presentations and a drupal back end for training they can track by user. We love Prezi and are thinking it would be a great way for their teams to build the presentations but my question is is integration with drupal possible? I would imagine simple URL referencing could work but the hitch is they want to track the progress of the signed in individual viewing the training presentation (i.e. how many clicks forward have they gone so if they log off and return it can continue from there or show the administrators they've viewed X% of the presentation but not all of it) and this seems quite a bit more complicated if theres not some more tight integration. Curious to hear what peoples experiencing putting Prezi and Drupal together are and if you have any recommendations.
