I assure you that it most cases the result has absolutely no sense, i.e. shows nothing.

If you want to tell that there are problems with software in our society, then yes, that was my original point. In my view the whole model of selling software is wrong. Because effectively you can only sell something, that cannot be copied with so little efforts. It does not work. I think that software should be considered rather as an insurance against its fault. That should be sold, not a stream of bits.

What I wrote about is not a joke. The navigation system, radio, CD player etc, all that will be connected to the field bus. They will also have Bluetooth and Internet connections. This will open wide possibilities for attacks of all sorts. -- Regards, Dmitry Kazakov www.dmitry-kazakov.de
