Mobile Marketing is the magic spell, here.
In past years I've been involved in software development for self-configuring wireless mesh networks at Wi-Next. Previously I hacked LSCube, an open source multimedia streaming platform project at Turin Polytechnic University.
I'm a long-time advocate for Free Software and Open Knowledge movements.
