John, My reply concerned providing a ubiquitous general purpose service for transferring bits, which is what Craig mentioned. This is not the same as a more specialized service, which would be a 24 hour a day TV broadcast. 3G cellular, and eventually IEEE 802.20, are specifically designed for such services. They are the wireless equivalent of your ADSL line or, previously, dial-up modem. That's what I call general purpose. I think one problem with trying to use one-way broadcast for "general purpose" applications is that the broadcaster has to guess at some content that the masses really really want. When you don't support two-way sessions, that's what you're forced to do. And that's where these schemes fail, IMO.
