The other issue is that you’ll only ever see very sparse adoption. So what can you really do with it?

You’d need some kind of kickstarter for a wifi router than implements everything you need plus this and then have apps that make use of it.

But in my country it’s basically illegal to have open wifi spots because you’re held responsible for any “illegal” traffic going on. So everyone has their own internet connection and isn’t sharing. And it’s only going to get worse.
