IBOCRocks said:That's akin to saying that the Windows Operating System could go to a subscription-based model. Sure it could, if the code was re-written and you actually installed it on your computer.
Since IBOC is essentially software, it could be modified to to that, absolutely. It's not able to do it in it's current form however. And at this point the consensus is that it makes no sense to move in that direction.
So, possible? Yes. Just as possible (and likely) that the satellite code could be changed to provide service for free.
They said that it was possible to do right now and that it was part of the original design parameters of the system. The only reason you can't do it right now is there are no addressable receivers.
I'm not trying to impugn your integrity. I’m just pointing out that it could become a pay service, and probably will. Talking Books for the blind come to mind, but it wouldn't be hard to expand on that to a variety of niche formats.
