It's amazing, really. Netflix and YouTube now overtake BitTorrent and all other file sharing peer-to-peer traffic combined, even on academic networks, by order(s) of magnitude. The amount of peer-to-peer traffic is not even significant in comparison. It might as well be IRC from our perspective. Internet usage habits have shifted quite a bit in the past decade. I think the takeaway is that if you provide content in a way that is fairly priced and convenient to access (e.g. DRM doesn't get in your way), most people will opt for the legal route. Something we were trying to explain to the MPAA and RIAA years ago when they shoved the DMCA down our throats. I'm certainly in favor of symmetrical service. I think there is a widely held myth that DOS attacks will take down the Internet when everyone has more bandwidth. The fact is that DOS attacks are a problem regardless of bandwidth, and throttling people isn't a solution. The other (somewhat insulting) argument that people will use greater upload speeds for illegal activity is pretty bogus as well. The limit on upload bandwidth for most people is a roadblock to a lot of the services that people will take for granted a decade from now; cloud backup, residential video surveillance over IP, peer-to-peer high definition video conferencing. And likely a lot of things that we haven't imagined yet. As funny as it sounds, I think Twitch (streaming video games) has been the application that has made the younger generation care about their upload speed more than anything else. They now have a use case where their limited upload is a real problem for them, and when they find out their ISP can't provide anything good enough they get pretty upset about it.

Those are measured at the campus boundary. I don't have visibility inside the school's network to know who much intra-campus traffic there may be . but we know that peer-to-peer is a small percentage of overall Internet traffic flows, and streaming video remains the largets.
BitTorrent makes special efforts to keep as much traffic local as possible, I understand; that probably isn't too helpful... except at scales like that on a resnet at a sizable campus.
