I will attempt to answer each substantive comment in a separate email, as I want to show the work in the form of a diff, and it will be too confusing to do it all at once. The tinyurl that I posted for Eric should remain valid as a cumulative diff as I push stuff to github, as rfcdiff will calculate again each time.
