And what happened to Comcast, Lemur? Do they still block torrent traffic?

Their attempt was pretty much total failure anyhow, as people quickly discovered how to circumvent their filtering. But, I think the topic of how ISPs- or even if they can- deal with bandwidth hogs is more interesting that the topic of net neutrality in general (your ISP is gonna block youtube!).

Hopefully, everyone realizes that bandwidth is not limitless. Your average user doesn't use that much of it, but a small percentage of users can and do take up massive amounts of bandwidth. Should an ISP be able to close ports used by bandwidth intensive applications like torrents? Most users don't use torrents, and those that do can slow things down for other users and adversely affect their surfing, ect. An alternative would be flat download limiting- which in my experience draws just as many howls of protest as port blocking. What to do?
