OK, maybe not really a true CMS but in working on this project, it was emphasized how important it was to make it simple. One of these days I’ll explain what it was for.
Update: having now left iStreamPlanet, I have no idea what ever happened to this. Originally it was supposed to be for live streaming of Sunday Night Football on iOS & Android via HTML5 but there were severe limitation imposed by the iOS in terms of playlists. We were working with DoubleClick to get through some of the problems (thanks to that team for some nice workarounds) but in the end, iOS prevents skipping to the next item in a live playlist unless the user causes a direct interaction (so no pseudo-actions via Javascript). Nonetheless, before the 4.3 update, it was working. Flawlessly.
