As has been pointed out to me privately, the SUP-720 does flow cache  
PBR support.  Now, if you consider a flow cache to be acceptable  
performance, and the flow descriptor fits within the policies that  
you wanna write and you fit within the performance boundaries of a  
SUP-720, well, that may be a suitable solution.
