Users more or less know what a gigabyte is, because when they download
too many of them, it fills up their drive. If the limits are high
enough that only actively using high-bandwidth apps has any danger of
going over them, the people using those apps will find the time to
educate themselves. It's not that hard: an hour of video conferencing
(500 kbps) is 450 MB, downloading a gigabyte is.. 1 GB.

But then that same 1GB can be sent back up to P2P clients any multiple
of times. When this happens the customer no longer has any idea how much
data they transferred because "well I just left it on and.....".

Really, it shouldn't matter how much traffic a user generates/downloads
so long as QoS makes sure that people who want real stuff get it and are
not killed by the guy down the street seeding the latest Harry Potter
movie. If people are worried about transit and infrastructure costs then
again, implement QoS and fix the transit/infrastructure to use it.

That way you can limit your spending on transit for example to a fixed
amount and QoS will manage it for you.
