Brian, Thnaks for clarifying that. I'm working on a whole family of specs (6on4, 6under4, 6from4, 6and4...) to confuse everybody even more :-) No, Proposed Standard doesn't require interoperability - that's when you go to Draft Standard. Yes, there were a couple of implementations of 6over4 around, but I haven't yet thought about doing the due diligence to see if we are ready for Draft Standard. There is at least one pending change to the 6over4 spec that we agreed on a year ago (a SHOULD NOT instead of a MUST NOT). 6over4 is an IPNGWG item. I have deleted NGTRANS from the copies.
