for them, it might but we need to discuss. It's not anywhere near as  
obvious as it might sound. In the end, it's about what kinds of  
guarantees they are asking for. In at least one scenario, the  
relevant folks are asking to be able to download a file of a stated  
size within a stated amount of time. To do that, I need to be able to  
predictably give the preferred traffic class, whatever it is called,  
a stable bandwidth. Drop priority doesn't accomplish that; it only  
accomplishes that the preferred traffic competes more effectively and  
therefore gets a larger subset of the traffic. I can fairly easily  
construct scenarios in which even the preferred traffic gets bombed  
off the link.
