To follow up on Jack's post, there were definitely instances of 'we talked
about it at the time, but didn't write it down until later' back then.

One good example is the 'fate-sharing' stuff - I distinctly recall first
seeing that in a presentation that Dave Clark gave to some DoD people in the
late 70s, but it didn't show up written in a paper until the 'Design
Philosophy' paper, in 1988, about a decade later.

As to the E2E argument: I personally don't recall that we had it in a very
articulated form in the late 70s. Maybe some people had it in their heads
(Dave Reed has indicated that he had it early on, and told others about it,
and then Jerry decided it needed to be written up). However, I recall the SRC
paper having a big impact on me when I read it, so I don't think I clearly
understood the ideas in it until I read it.
