Lets go way back to wearcomp [0] with steve mann [1] and cyberman [2] before we get all misty eyed. I'd really like to see something more than just a camera. Mann has gone a step beyond mere transmission with augmentation. Better still go look what students & mann are looking at now. [3] The tech details are here. [4]

Q. Does jtv have the ability for users to communicate? Or is it unicast?
