Having the routers cache id-to-loc mappings is one thing; having them perform id-to-loc mappings is something else entirely. Yes, the hosts will still generate such requests, but those requests don't have to traverse the entire network if the local router knows what to do with them. But a lot is being assumed by the above statement. I am fairly convinced that id-to-loc mapping needs to be more like mobile-ip where you send a packet to the id and get a redirect to the loc if the network can't route to the id, than like DNS where you make an explicit query across the network and get a response.
