Alright, I was generalizing a bit, and the data I quoted was from one particular manufacturer of traffic shaping/DPI equipment. In any case, the general consensus seems that "real time entertainment", i.e. streaming audio/video make up 40-60% according to all parties, fairly close to half of all internet traffic with some variation by region.

And P2P traffic, in the downstream, varies from the high single digits to low double digit range, which is fairly close to what I quoted anyway. Again patterns will vary by ISP and region, but shaping what takes up 10% of your bandwidth down to a maximum of 25% of bandwidth (well, with NNTP included) was never going to have much effect - that is of course if VM are actually doing it as they say they are.

Even in the upstream, if P2P is using ~35% overall and ~30% at peak times, capping it to 25% really won't reduce overall traffic by more than 10% if you look at it logically. We can pretty much ignore NNTP here since, well, there is negligible amounts of upstream NNTP on a home user's connection.
