At first I thought you were right, it's all about the buzzwords, nothing much new. But then I noticed they are talking about to or from ANY vehicle within a 30-mile radius. With the simple FM broadcaster, you have very limited range, as well as a limited number of channels not already in use by regular radio stations. So provided that the WiFi (802.11p) ad hoc network properly handles all the nodes in the mesh, you could be *casting many more stations than are currently available in the FM spectrum. (see, you have to use all the buzzwords in the same sentence)
But if it ever happens, it will simply crushed by the RIAA as piracy on the open road, rather than on the open sea.
