Yes; in fact, what would make it an instant killer app is the fact that half (if not more) of global P2P traffic would instantly drop from the backbone, disappearing into the local meshes, with hopefully a majority of data requests being satisfied by the local caches made out of mesh nodes local storage. That would not only decrease the load on the backbone and anonymize the traffic, hiding it inside local nets, but also increase the P2P client average throughput, making it possible to stream movies in real time and whatnot - which is a killer app in itself. Actually, David Barret had already suggested something like that recently: http://blog.quinthar.com/2011/01/how-piracy-will-hyperlocalize-with-mesh.html - albeit with software radio instead of the existing wi-fi hardware. So David, since this mesh hyperlocalization was your own idea, I'm not sure - why would you suggest that ther's no compelling value in mesh networks, even with normally functioning Internet? Except for this pesky ubiquitous wi-fi encryption, of course...

There's still a lot of academic research into ad-hoc networks, but I'm not aware of anyone really pursuing something like this in the commercial space -- anyone been following closer than me?
