>without a reliable infrastructure. Data broadcasting is a completely valid concept; Geocast, iBlast, et al have not been able to get the business off the ground for a few simple reasons: >1. The DTV transmission infrastructure is inadequate to support a commercial data broadcast service. And even if all stations were broadcasting at full licensed power, the percentage of sites where reliable service CANNOT be established is too high for a viable commercial launch. Good point but one little problem - Geocast was satellite-based. As were others such as Cyberstar, Astro, ... >2. Without a reliable infrastructure there is little incentive to develop the receivers necessary to launch such a service. You don't have to believe me...just ask Dewey. That's true. Reception is the usual killer. And a percentage of the first trial group usually has a problem with reception. But the killer has always been lack of a business plan. What do you sell on the datacasting service? Website caching? Nope, got that on Cable/DSL. Movies? Nope, got blockbuster down the road, or cable/sat. tv. Games? Nope, got Gamespot on the Cable/DSL modem. News? Nope, got the paper at the doorstep for $1 - why do I want a $300 newspaper receiver? If not, I use my Cable/DSL modem. Distance Education? Nope, colleges are already using Cable/DSL. You might say that there are lots of scenarios here that will work in a different variation, but the difference is that I've lived all these scenarios first hand and seen companies fail at attempting to deliver this content, whereas you are just pipe dreaming about it. The only type of datacasting that works is non-consumer oriented i.e. professional or government services. Consumers are just too fickle to please in this day and age.
