Flash Radio! Is it do-able?

A friend of mine’s band (whose site I’ve made for them) are releasing their album early next year. And they are wanting to, as a surprise for their most loyal fans, have an early preview of their album. The thing is, they want to say “OK, at 9pm on so-and-so day we’ll be playing our album live from start to finish, just the once”, just like a radio station sort of thing. And then their fans can tune in and hear the album. Not rewind or pause, and if they turn up late, then sorry. So the MP3s are playing live, I guess.
Have I explained this poorly, or can you wonderful Flash experts ‘get’ what I tried to achieve?
Is it do-able? Any other suggestions? Many thanx in advance.
