Ok, that was a little bit of an exaggeration but two years ago P2P was dominating internet traffic and now, while still dominating the upstream networks, P2P is starting to drop in relation to real-time traffic. I see the time, in the relatively near future, where P2P is a niche market in comparison to real-time traffic. This is not to say that P2P usage will drop in absolute terms, only that gaming, VoIP, online file storage, movie, real time news and sports is going to increase tremendously over the next few years.
What will this do to theNet Neutrality arguments? Real-time communications can be buffered for only so long; a web page can be delayed for 500ms without too much complaint and an email can be delayed for 1000s of milliseconds without notice.
