How to dynamically stream music? HTML5 Hacks? - Challenge

Hey, I am trying to create a multi-streaming program that will take a song from my server (that is uploaded) and then play it to all my listeners. I should be able to start a new stream whenever I want (Dynamically). If no one can help me figure this out (I know there is a way via python - Java?). I am thinking about settling for now on HTML5 audio playing, but when new people join... how do I let those people come in at the same time the current listeners are listening to? I was thinking just grabbing the current time and making the song for that user begin at that time... but then there is bandwidth delays? Any intelligent people out there have any solutions? You guys are the best!
