I'd love it if they released some real-time data. Imagine an iPhone app that gave you the position of every tube train and bus in the city.

  It is good that mobiles do not work in the tube, as real-time position information is a security concern.

    I never really understood why that would be the case. What can people do with that information that they couldn't do otherwise?

      I was implying more GPS-synchronized bomb triggers.

        Sounds like more of a movie plot threat than anything worth worrying about. If you really want to do that attaching your own GPS device to the bottom of a bus (or just having an observer with a mobile phone) is easy enough as it is.
