Level3 routing issues?

What about doing some priority-based QoS?  If a single IP exceeds X amount
of traffic, prioritize traffic above that threshold as low.  It would keep
any one single host from saturating a link if the threshold is low.

For example, you may say that each IP is limited to 10mb of prioirty
traffic.  Yes, a compromised host may try to barf out 90mb of chaff, but
the excess would be moved down the totem pole.

Obviously, this may not make sense in all environments, but in a campus or
large enterprise situation, I can see this occuring on your WAN links in
particular.
