Dogs & cats living together MASS HYSTERIA!!!!
Part of what makes a cable cellco so impossible is the fact that you need the cable industry to work out a business model where they all share network resources and profits and that is unworkable. This is like Verizon trying to work with Centrury tel to breakout to be a power company service provider. They're not even part of the same GRID...
*There are of course greater possibilites once fiber is available just about everywhere... in every city & suburb (end-to-end, not just run a bundle to the border). This would take MASSIVE investmetn by the tier-1 companies and is nowhere near a primary goal for them yet.
