I believe all IPv6 nodes SHOULD support IPsec. I don't care about the PKI or other managed parts but if they are referenced to IPsec they should have no known protocol interoperability problems, the market will decide and select on that one is my view. This should clearly not mandate USE as others have stated. I also would support a MUST as I agree with Dow and others who can see the value of a MUST but I will not fight to hard if majority wants to move to SHOULD. If it is 50/50 for consensus I will continue to provide data why MUST has to remain. And I want to reiterate and note the important mail from Tony Hain for this polling to others as input to our collective thoughts.
