One thing they did not mention is that this solves the primary problem with orbital crowbars (fictionally called "Rods from God", "Thor", KEWs, and various other things). You could drop a kinetic warhead (basically a crowbar) from orbit to kill a tank / bunker / whatever, but you could also use them for a variety of peactime missions such as mining, emergency flood control (digging drainage ditches, causing controlled landslides), etc.

Each crowbar would need some sort of minimal steering system to account for atmospheric turbulence. This steering can't be locally controlled because the device can't see past the plasma sheath. It can't be remote controlled because the plasma sheath stops transmissions. With this new "plasma aerial" technology, you could steer each crowbar individually from the launcher platform.
