Right now Comcast (except for torrent traffic, fuck them for that) doesn't meddle in what the packet is or where it's going, per se. However they do, apparently, have peering agreements with companies which allow these companies to serve traffic directly from THEIR networks, straight into Comcast's networks. This effectively does favor certain traffic over other traffic, but it's a kind of favoring that's been going on forever, and is generally accepted.

I dunno. I actually fail to see how peering in general is not a violation of net neutrality, however it's so critical to the smooth operation of the Internet, I'd rather have peering than net neutrality, if I had to choose.
