The Just in Time (JIT) lecture developed by Rashid Chotani was a crystal clear example. He uploaded a lecture on SARS story just as it appeared. That was a unique experience for the world who were along the head of virus as they were able to prevent the extension with Supercourse. The lecture was being updated every 2 days.
