Yes, we are familiar with QPPB.

We use it quite extensively for one of the products we sell; 
and yes, it is very neat. Offers far more scalability and 
manageability for providing restricted access (and 
services, thereof) to specific routes in the network.

However, for the particular situation I described earlier, 
we feel a VRF would be a simpler solution, especially on a 
software router.

Juniper's DCU feature also accomplishes the same task as 
QPPB.

It's supported on the 7200-VXR.

This is due to a hardware limitation on these particular 
platforms. Have a word with your SE for details.

Cheers,
