What makes you think the same attitude which allowed DAB to fail
would not be same attitude which allows any future DRM service to
fail. As in trying to put two or three radio stations into the same
capacity which is only suitable for one.

again but this time against DRM ?


I cannot be bothered to respond to your comments about kb/s or kbps.
