@jwildeboer I especially like the idea of "ad hoc upgrading" the bandwith in crowded places. WiFi is expansive (edit: should have been expensive, but it's both ), so there would be some mechanism needed to not drain single devices. Like a flag getting sent around by the devices having wifi up indicating the saturation or "reachability of targets" so other devices could jump in dynamically. Combined with a time based rule, like: Wifi up no longer than 30 minutes in a row for foreign routing for a single device.
Yeah, I think I like the gerneral idea.
