The p2p limit is artificial, but would the service be limited for
everyone if that limit isn't in place? If not, then Comcast is blocking
a useful service for no good reason. But if it is, then I can understand
their point of view. While it sucks to be that one guy, it doesn't
really make sense to let everybody else's service degrade.

Let me give you a better example with some hard figures. As you may have
inferred (I certainly do not attempt to hide it), I work for an ISP. We
offer wireless service and occasionally will see problems caused by p2p
filesharing. The problem isn't the bandwidth (I've got upload bandwidth
coming out my ears) but packets. We'll have a tower where one user is
sharing files and causing decreased service to maybe 50 other customers.
So we put a filter on the user's IP and call them up and ask them to
stop. It's a courtesy to everyone involved since due to one user's
actions, everyone (even the customer in question) is being hurt.

The situation for wired providers is different of course, but it's not
always economical or technically feasible to redesign the system on a
whim. What exactly Comcast's justification is I can't say. I wouldn't be
surprised to hear that it's nefarious, but it is possible they're
actually trying to do a good job.

Higher priority tickets, direct access to our network engineers, service
monitoring (Nagios style). We often throw around extra services like DNS
hosting and backup MX, that sort of thing.
