It's a trend: several people have built usable Wi-Fi hotspots that use a variety of techniques for backhaul to bring access to performance venues, outdoor events, and disaster sites (reg. req.; get generic user/pwd): The latest wrinkle is a musician and tech entrepreneur who uses an old TV transmission van to connect to his wireless broadband receivers around town. He has transceivers on top of skyscrapers used to bring point-to-point wireless to his Implex.net customers, but coincidentally offering him backhaul for art and music projects.
The article also talks about bikes, mopeds, and golf carts equipped as hotspots. With the addition of a system like that from Junxion, any vehicle with a cigarette lighter within cell data range can become a mobile hotspot, too. And then there's the planes, boats, trains, and buses coming down the pipe.
Escape Wi-Fi? Never! Not even if you want to.
