I think it's safe to assume that isps are steering p2p traffic for the 
purposes of adjusting their ratios on peering and transit links...

while it lacks the intentionality of playing with the usenet 
spam/warez/porn firehose a little TE to shift it from one exit to 
another when you have lots of choices is presumably a useful knob to have.

Layer violations to tell applications that they should care about some 
peers in their overlay network vs others seems like something with a lot 
of potential uninteded consequences.
