from the fAQs i gather that it sends from one gotenna to one or more recipient gotennas only: "Your smartphone will send the message to your goTenna, which will then shoot it out, via long-range radio waves, to the intended goTenna(s). At the other end, the exact same thing happens, in reverse: the recipient goTenna sends your message over BTLE to the smartphone app its paired with." https://gotenna.myshopify.com/pag…
goTenna is an ad hoc reconfigurable network in that you can create your own network (1:1; groups, 1:all; all:1) but we can't currently mesh due to FCC regulations. So we went with long-range instead, since meshing is most useful in dense, short-range situations. We're on it though... ;)
You could charge for access to internet side of the store and forward system. Maybe attach cryptocurrency to the messages to pay for routing across the POPs.
