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."

building an ad-hoc network with these things would be kind of cool though. DIY city networks anyone...

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... ;)

This could be earth changingly huge if you open source your designs and make one with wifi/ethernet. Store and forward push to talk messages.

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.

Are you using the TI chips?

The platform possibilities are endless. Our dev kits will be ready soon: http://bit.ly/1oRwBkI
