Second Life brain power

Is this - using brain waves to control SL avatars - for real? If so, it is amazing.

All a user has to do to control his/her avatar is imagine performing various movements. The activity monitored by the headpiece is read and plotted by an electroencephalogram, which relays it to a computer running a brain wave analysis algorithm that interprets the imagined movements. A keyboard emulator then translates the data into signals which can be used to control the movements of the user's on-screen avatar in real-time.
