Streaming with contraints

Let me be clear about what I know about my personal situation. I have a 4g jetpack it works pretty flawlessly anywhere we have been on the east coast. ( I would consider Canada and Mex pretty much outside the range of the "norm") I can stream whatever I want and all day if I wanted to. I can run a dual encrypted VPN as well as 4 other connections without seeing too much degredation in bandwith. The technology is there. It's there for portable devices even as far as using some phones as a hub. It's there. The companies streaming media have the media. The obstacle is cost. There is no solution to leverage existing technology that's not cost inhibitive. I am struggling with how this model will grow and evolve unless cost and constraints are addressed. That's my point.
