Are you thinking of scavenger on the upload or download? Because it's just
upload, it's only the subscriber's provider that needs to concern themselves
with their maintaining the tags -- they will do the necessary traffic
engineering to ensure it's not 'damaging' the upstream of their other
subscribers.
If it's download, that's a whole other ball of wax, and not what drove
Comcast to do what they're doing, and not the apparent concern of at least
North American ISPs today.

Actually, it sounds a lot like the Electric7 tariffs found in the UK for
electricity. These are typically used by low income people who have less
education than the average population. And yet they can understand the
concept of saving money by using more electricity at night.
I really think that a two-tiered QOS system such as the scavenger
suggestion is workable if the applications can do the marking. Has
anyone done any testing to see if DSCP bits are able to travel unscathed
through the public Internet?

P.S. it would be nice to see QoS be recognized as a mechanism for
providing a degraded quality of service instead of all the "first class"
marketing puffery.
