I have been more focused on the initial VRF infrastructure and have not 
spent too much time on these use cases or other route lookup features 
(e.g., allow an application to handle route lookup misses similar to arp 
misses, allow custom route lookup modules) that are needed to approach 
the feature richness provided by high end routers.
