I believe you're correct there. A smaller group could also connect via Bluetooth. My understanding of the functionality, as far as a rural or remote community goes, is that everyone joins together in the app and as people create content via chat/forum/blog, the app connects and updates that information as people get close enough in proximity to connect individually with each other via wifi or Bluetooth. So if person A comes in from their farm and sits down at the cafe and they belong to a group(s) with person B who's already there, person B ends up sharing all the updated data in the app with person A who can then contribute their own information that anyone in the cafe that's connected will get and then be able to update those they come in contact with. ...at least I think that's how it works.
