I have a question about the ip reverse-path verification. Obviously, it
won't work very well in asymetric multi-homed environment. But, the
usefullness could be there (even limitedly) if you could at least filter
packets that have source address which does not exist in the routing table
_at all_ (irregardless of ingress or egress interface). 

Is this something that could be implemented easily?
