We are using radius, this would be the least painful. We have the 
speeds in the database and can pass them back via radius easily.

Is most of this handled on the PA or will it cause a huge processor load 
increase? We are currently terminating to a PA-A3-OC3

I'll give that a try.

Would it be reasonable to use priority queueing instead of basing 
QoS/allocation on bandwidth of the subinterfaces?
