If Zediva really has a DVD and player for each film they are showing at any given time then it is exactly like a DVD rental service via mail. If there's 10 people watching a film right now and they only have 10 discs, me being the 11th person would not be able to stream that movie until someone else finishes (returns) one of those 10. Netflix is a streaming service where they have a 'single' copy of a film that they can stream to an 'unlimited' number of people at any given time.
