Unfortunately, as we learned from the debacle of cellular communications, corporate inertia will either squash this or slow gestation until it's stillborn. There is a substantial investment in the current technology of TCP/IP and it still works "just good enough". This change in network would require installation of a twin network alongside the current, with slow adoption in the consumer side. That would be very expensive to build and maintain over numerous financial quarters and thus no MBA-centric company would ever do it in current corporate culture. This takes long-term thinking in a quarter-to-quarter environment. Thus it won't happen for a very long time.
