A new technology venture from Napster co-founders Shawn Fanning and Sean Parker. Set to launch in late 2011, Airtime is intended to be a mix of Chatroulette and Facebook - a system that allows for the random introduction of two strangers but also containing a social network to keep people in touch.

The project has already seen heavy investment from some big names, including actor Ashton Kutcher and technology expert Marissa Mayer.
