Absolutely, they start shredding the "we're just a pipe, like for water ya know?" defense. Additionally it begins to open them up for damages due to service interruptions. Imagine someone that legitimately uses torrent services to transmit large work-product files...say a graphic designer. Now imagine that person is unable to send an important deliverable because Comcast has been mucking about with their connection. I'm in no way saying it's a slam dunk to prove they did it or prove damages but it certainly edges them a lot closer to taking responsiblity for economic effects of service disruptions.

Encryption is good, use it.

@Cowboys_fan:
Yeah, encryption... because your dealyed or dropped packets aren't slow enough already.

Ture, while it might stop the ISP from figuring out what's in the packet and therefore maybe stop them from interfering, maybe instead we should be asking "why do we have to get into an arms race with our own ISP that we pay to carry packets for us?"

As Buran points out, how about just getting them to do the right thing, rather than the probably illegal thing?

Encryption!

Does an ISP have the legal right to block or slow down access to certain sites based? Or is it a situation where they can do whatever they want?
