Is there HTML embeddable audio player which prevents downloading of the audio it plays?

I'm looking for an audio player (like jplayer) which can be embedded in a HTML page which will allow MP3's to be played but not downloaded.

The problem: Flash players request the audio file from the server so the URL of the MP3 is present 开发者_开发百科in the HTML source and can be copy/pasted in to the address bar to download the track. This will inherently be the problem with most players.

Possible solution: The player accepts some "encrypted" (non-playable) format which is then decoded inside the player. Anything like this exist?

I am not looking for solutions which sound like:

• Obfuscating the URL of the MP3
• Preventing downloading of the MP3 from third party sites (eg. forums) using .htaccess
• Embedding the mp3 inside a flash movie unless this can be automated, since mp3's are uploaded on a regular basis.
• Having a URL which only works for a certain period of time

I don't know if this answers your question, but... Have you tried streaming your audio files via flash? I have never heard of someone being able to download a file which was dynamicly called through actionscript... but maybe i just don't know what i am talking about...
