In your previous mail you wrote: This entire question is being begged by multihoming which RPF checks fail at pretty miserably. And of course, asymmetric routes. We need something better. Essentially, I think what I'm proposing is something in lieu of RPF checks. The open question is whether we can make this pervasive too. If we can, we can safely turn off RPF checks. => the idea that RPF checks always fail with multihoming is a myth (cf http://www.cisco.com/public/cons/isp/documents/uRPF_Enhancement.pdf).
