It was a business hard won against bullets and bullies in the tough South African townships. Now Luvuyo Rani, the man who started a multi-million-dollar tech business by selling out of the boot of his car is telling the rest of the world how tech entrepreneurs can bridge the so called "digital divide".
It is just after breakfast on a crisp spring morning on campus in Boulder, Colorado. Rani is chipper, far from home, and ready to talk. His ready laugh speaks of bitter-sweet experience.
This is one reason why the professors at the 150-year-old University of Colorado, an institution that produced three US Supreme Court Justices and five Nobel laureates, invited Rani back this year.
