Just heard the BBC Radio 4 piece that Hugo was interviewed for. They used two bits from him, one about the invention of mp3mobile and the other about the failure of motor manufacturers to "get" the empeg.
There was some wonderful nonsense from the motor industry representative put up for the interview. They were asking him why car manufacturers couldn't just provide a simple plug for plugging external audio devices (iPod, Karma etc) into. He suggested that it hadn't happened because of concerns over safety, security and engine performance !
Unfortunately at no point did Hugo get to mention Rio, the only MP3 player mentioned (apart from mp3mobile and empeg) was the iPod.
The show was "You and Yours", at some point later today or tomorrow you should be able to listen to the show by going to
