Hi,

At first sorry for the delayed reply.

Please, see my comments inline.

I agree with Jari:
(1) IMHO, this would be like to put the cart before the horse :)
(2) to doing such an analysis you need a clear specification of a SAVI
mechanism which is outside the scope of this document. BTW, during my
review of FCFS SAVI for the ID Write-Up document, text about residual
threats was added inside the Security Considerations section. I will
carefully check that the DHCP SAVI, SEND SAVI and the Mix Scenario
documents take into account this issue before requesting AD/IESG
review.

Best regards.

JMC.
