Gorry -
Another minor point, for the next revision: Checking through the cited documents, I am reminded that TFRC [RFC3448]predicts the future emergence of TFRC-PS (which became finally TFRC-SP).A word in the introduction noting the relationship between the TFRC-SP andthe TFRC-PS is probably also worth adding?
Thanks, done. - Sally http://www.icir.org/floyd/
