Ad hoc wireless has kept being reinvented all the way back to 70s, or
maybe even 60s (I haven't done my research), each time with a different
(mostly colorful, e.g. "munchkins") name.
What this time is different is that we have solid state integrated radios
and enough crunch to put most of the radio into software (or rather
reconfigurable circuitry). Also, we have another technology --
ultrabroadband, or digital pulse radio -- which is extremely suitable for
small scale high throughput ultralow power meshes.
Another key concept with ad hoc wireless is geographic routing (routing
packets as the crow flies). This has varios advantages over such WAN
protocol monsters as IPv6, especially if you want to scale to planetary
sized networks.
I wonder how long it will take until we'll get all three components (ad
hoc, ultrabroadband and geographic routing) in one place.

"And the always creative Benjamin Franklin once expressed his desire to be
preserved in a cask of madeira with a few friends so that he could see
what had happened to his beloved republic after several centuries. But
Franklin despaired that the technology for dealing with these problems
would not arrive in his lifetime, and of course he was correct."
