Hi Tom,

There are a couple of ways of doing this in real time without clearing the 
session:

* use service manager to change the QoS profile. Service manager is a hefty 
feature that can do various subscriber management magic, such as on-box volume 
and time quotas. One of the other capabilities of service manage is to be able 
to change the user's QoS profile. It's a licensable/chargeable feature tho.
* switch to using policies to cap user bandwidth and use RADIUS CoA to change 
session rate limits.

Cheers,

Chris
