The lecture hall is closed

When I walk past this room at SJSU, several times a day, it is full of students sitting and note taking while their professor, the sage on the stage, delivers a long verbal lecture. This photo was taken using my cell device. This device can take pictures, movies and even receive and play audio mp3 files. There is no reason this device, and/or smarter small devices like this, couldn't receive the lecture content as a part of a podcast and then the student, at the time of his/her choosing, could consume that content. The student could interact with the professor through a weblog or a learning management system, like Moodle.
