  2. Changes since -00 • Responded to reviewer comments • Sally Floyd, Gorry Fairhurst, and Magnus Westerlund • Increased focus on RFC 3168-style ECN as the capability to be supported by this draft • reduced emphasis on PCN - now serves only as an example of how scheme could be extended to more complex scenarios, mostly relegated to an appendix • removed irrelevant reference to re-ECN • Clarified the rationale for preferring the ECT-checking approach over the approach previously proposed by Floyd et al. • Clarified relationship to tunneling behavior specified in RFC3168

  3. Conclusions • Draft now does not depend on PCN making progress - stands on its own without PCN • The substantive technical meat of the proposal has not changed for several revisions now • Recent changes are minor and affect presentation rather than technical content • Hence, we think we're ready for last call.
