One of the things you could do to make the recording process simpler is have something like a dropbox folder that people can send their shows to, straight from their phones when they are done. That way you have a one-button upload without having to develop an app right now.   The second thing I would find cool if is there was a Telegram or Voxer channel for HPR listeners / hosts. That way we could talk to each other and (in a pinch) these audio conversations could also be used as a show.
