Metered goods have a long history of having to have the meters certified by state bodies.

For instance, grocery store scales, gas pumps, power meter manufacturers, etc.

If we're going to lose the fight with Comcast over metered bandwidth, then perhaps we need to push for laws regarding inspection and validation of their metering systems themselves.

If they're limiting consumers to a certain amount of traffic, I want the definition of traffic to be clearly delineated and for the measurement systems to be properly inspected and regulated.

For instance, do they measure at the modem? At the local node? At the edge of the network?

Does local traffic within Comcast's city-wide network count?

If someone sends an IP traffic that their computer never requested and is filtered out, does it add to the traffic usage?

Does a UDP broadcast in a subnet count towards everyone's bandwidth, even if the cable modem filters it out?

Does this cover ICMP and UDP?

Does Comcast's own "Are you there?" packets to cable modems count towards traffic allotments? Does Comcast's cable modem traffic to the registration and DHCP servers count?

If they're going to screw-over customers, then there needs to be clear rules they have to follow so they can't just make up numbers. There also needs to be a way to make sure that DDOS attacks can't attack the bills of customers.
