I don't think I'm breaking a confidence when I say that we on World Update have been told to wait before podcasting.
The BBC is carrying out pilot studies in what kinds of programmes in which form should be turned into podcasts.
I'm still pushing: World Update is aimed in part specifically at the US audience - who have the best access in the world to broadband Internet, which makes podcasting work efficiently.
I was given extra drive by a conversation I had with a teenage friend over the weekend.
He listens to a lot of radio, he told me. But he hardly ever uses a radio to do it.
He's signed up to several podcast from his favourite radio stations. And his favourite radio stations are doing 'best of' podcasts.
He's not listening to music. He's listening to news and talk shows.
On podcasts, he tells me, he gets much better value for the time he spends listening.
As the technology gets more sophisticated and helps him make even better selections, I'd guess he's not going to be a radio listener in the traditional sense.
Radio on demand is his vision of the future.
