Ionized plasma crowd control

In another example of sci-fi making the leap to the real world, a company called Xtreme Alternative Defense Systems (should we really trust any government contractor with Xtreme in its name?) claims to have developed a wireless stun gun that conducts electricity through ionized gas and can take out a crowd of people. Currently the range is under three meters, but they're hoping to bump that up to over a hundred. At this point it's all up for debate, since the Slashdot folks have noticed that the company's website is on a free hosting service. On the other hand, they do have a contract with the Navy, so it remains to be seen whether or not this is real. The picture on their website is less than reassuring. Though that is perhaps part of the plan. No one would expect something that absurd-looking to fry them from a hundred yards away.
