What you didn't tell him is that the kind of shaping you can do
on the BRAS heavily depends on features used and platform. :)
64k policing mostly works everywhere, for example, but isn't
all that crash hot for your clients. :)
Doing more complicated hierarchical QoS on software platforms is
doable but complicated.
Others take a multi-tiered approach - they'll buy some kit to do
P2P identification/shaping, and per-user hard shaping in case they
go over quota.
Lots of cute stuff. :)
