Chris would you mind sharing more detailed info on how you hosted the special URL with Amazon S3? I need to host a URL for an audio broadcast not video. I was using jwplayer but was having issues with it playing through a WordPress page in Firefox. It works in a static HTML page no problem though.
Originally I was trying to figure out a way to have a session or cookie that when a user logs into the membership page they are given a URL (so it can be played in any media player on their computer or device) but cant share it like you mentioned!
Im working on a project for sports broadcasting that would be broadcasting to listeners all over the world. Im trying to bring this service back. Previously they would have 20,000 + listeners.
Its a big, but small project for me. I have all the broadcast stuff figured out, except this way of avoiding browser issues.
