audio streaming that cannot be saved?

Question

I need to publish a audio file that I want to make so that:

• It is available to listen in streaming.
• The file can't be retrieved for private use.

Any idea how to do it?

Something where user cannot save the audio using any webbrowser plugin like DownloadHelper would be the best, but already preventing the everyday user to save the source file on his machine with a right click would help.

The only option I know that is resistant to header snooping (DownloadHelper, Live HTTP headers, etc) is by using RTMP streams, which is a true stream rather then a play-as-you-download stream. - en.wikipedia.org/wiki/Real_Time_Messaging_Protocol

I don't have any experience in deploying rtmp myself, but I know there are multiple solutions out there for playing, like flowplayer: http://flowplayer.org/demos/plugins/streaming/multiple-rtmp.html

I know MySpace switched all their artist playlists to rtmp and it's kept basically everyone out - although we can always record the output of the player using desktop software like Audio Hijack Pro:

All this being said, I have seen a commandline rtmp stream ripper, but never got it to work. In the end the best protection is minimum quality rtmp streams.

Hope this helps!
