I think the idea here is that somebody else runs an underlying IP layer, and this rides on top as an overlay network. You could, of course, run a local wireless IP layer and use this to route, but peer-to-peer wireless has well-known scaling problems. Still, it looks like a very interesting and reasonably well thoughout out idea.
