 About three or four years ago the BBC brodadcast quite a lot of
radio drama using a technique which had a similar effect.  You
had to listen on headphones.  I can't remember what they 
called it, but I'm fairly sure it wasn't 'Holophonics'.
I seem to remember it working pretty well, I'd be interested
to know if it was the same technique,
