One thing most "electronic guru's" forget about ... you can go to a community library or a public college and use high-speed internet. Sometimes, a small fee if you're not a student, or member of the library.
When I first began traveling (working as nature and wildlife journalist and photographer), cell phones and hot-spot internet were not even thought about yet, let alone on every belt.
So, I would "save up" my internet needs, and take one day a week, spend a few hours of it at the library or college, and send everything off that needed sent, check emails etc.
It worked very well, and I spent more than four years on the road in a truck camper and pick-up. No need then for a toad, as the camper just dropped off and the pick-up took me around to the work areas and groceries. I even used the college gyms about once a week for a very long and hot shower - even tho I had a shower in the camper - it's nice to take a longer one at times.
So, for what it's worth, that might solve the HD internet use when necessary, and a Verizon hot-spot for the rest. It's very unlikely you will find any WIFI service that will provide gaming and movies etc -- way too much bandwidth use, and the expense per unit will kill your wallet.
I can tell you tho' the feeling that hit me the first time I was able to send in an assignment direct from a mountain top above Sun Valley, Idaho was an amazing experience. Today, that's like no big deal ... but times change, as does the internet potential, and it changes pretty quickly.
Who can predict? But I expect communication companies will eventually accommodate the traveling public and work-force with WIFI that will service video-streaming products. A few years ago, who would have thought you could aim a phone and send a Selfie you just shot half-way around the world, and anyone with a cell-phone that was actually interested in your Selfie could see YOU instantly !!
last time I talked with my grandmother, she still described living in a farmhouse with no electricity and using the outhouse in Clearfield, Pennsylvania. We've come along way in the century she was on earth, and change comes faster every year.
