We are about to launch (as soon as we can figure out who should host it) a 60-hour gmat course by full-screen (!) streaming video. It's very important that the student see everything, because the teacher teaches with a whiteboard, and draws and writes all over it. (Just like in a class.) But the compression is just less than 400kbps and there are, as I said, 60 hours of lessons. Also, the students will come from anywhere, all over the world. How do I choose a hosting service? What type of mirroring do we need? What else do I need to know? We want to keep the videos in wmv format. Are we wrong? PLEASE ANSWER AS FAST AS POSSIBLE.
