In the surviving source code, BBN VAX TCP re-purposed the ‘mode’ parameter of open() to be a pointer to a block with connection data (“struct con”). Details are here:

That's... clever? Gross? I don't even know how I'd want to react to this...  which likely means "too clever for its own good" :)

In any event, I've created a short, 2:00 correction to my talk. I'll have the conference organizers tack onto the end before they upload it to youtube.

If people care :)

Thanks everybody for corrections...
