WifiKill for Android

[Cipher]

This isn't available on the market, but it's awesome.
It basically disconnects clients from the internet on a network, so you could connect to a public network at McDonalds or something and kill everyone off of the network :D
The only downside (for people who don't have root) is that it requires root access.
You can grab it from here: [Only registered and activated users can see links. ]
