I think you may see more than average numbers of creative types at a university environment. Once you have a full time job you tend to have less time for "creative endeavors". I can say that having thousands of customers, the content producers are definitely a minority. I would even guess that most of your creative users still download more than they upload. It is simply math. A single person cannot create content as fast as they can consume it. The traffic is even becoming more asymmetric. You would have to create an awful lot of music and video collaboration and lots of documents to rival that 4K movie you want to watch. I can watch a movie every day without too much effort. I would be hard pressed to make that much music or content of my own. I am talking about real compelling content with value not an HD camera staring at a wall. Even backups are rarely an issue for the average user as long as their backup solution is intelligent enough to use bandwidth efficiently. Really, the average user's circuit is sitting idle most of the time in any case so if that backup takes all day to complete, no one cares. On this group we have to watch that we do not see ourselves as the "average user", we definitely are not. Bottom line is that symmetric technology is actually easier (and the original DSL technology which was mapping symmetric TDM channels onto copper loops), users just don't want to buy it in most cases. ADSL is what users want.
I guess I know more than the "average" number of creative types who might be interested in things like video collaboration, music/video recording, sharing around large hunks of content to edit/modify/etc., and of course my >>previously mentioned hobby horse, backing it all up in a timely manner to someplace maybe not in the path of seasonal hurricanes :).
