It's a very cool idea, but the first barrier that comes to mind would be that when the clients join the hotspots, they don't have internet access, so joining the network would mean losing internet, for laptops and phones without cellular data. I know the LocalOnlyHotspot API I use on Android doesn't offer internet tethering. I'm not sure how possible it is to ensure that on Windows and Linux devices that host hotspots. Also, the device that offers the hotspot in Flying Carpet is pretty much acting like a normal WiFi access point in infrastructure mode, so a real mesh network would probably look a lot different.

Thanks. Those are the kind of issues I was worried about with a superficial glance. The general idea looks tempting ("send files to nearby devices"). However, dropping connectivity every time would probably be a deal breaker. I was hoping you might be able to connect for like 10-20 seconds, grab a few kB of files, and then continue on your way, having a spotty, partial connectivity to other devices while wandering the above mall scenario.
