Tnx Barry. That is the video I saw. (and then couldn’t find it again). I also
watched the previous one of how lockouts worked.
Perhaps it’s really not long enough to draw any real conclusions, but just as
one example, I see the 2 x 40m stations alternately transmitting back and forth
and neither one changes frequency(no padlocks on screen or lockouts appeared).
Now, to be fair, perhaps one is running and one is calling a
difficult-to-get-through-to station on the other frequency(for at least
1:12seconds). Without clear evidence, I cannot say. One of those ops is you
on 7.035MHz.
I see one picture of one padlock on the 15m station.
One 20m station appears stalled on one frequency, one is running and one is S&P…
So you can probably at least see why I asked the question.

Mike,
There's a link to a short youtube video in the 3830 writeup for WW1X that shows
how the lockouts worked ( https://youtu.be/Os7s-Y_gngY ). As one of the two
40m ops, the lockouts worked just as well as the hardware lockouts in an
in-person M/M. There was a learning curve to not interrupting the run station
too severely with S&P QSOs, as it was very different from seeing a visual cue
from the person sitting next to you. By day 2, we seemed to be in better sync.
To the best of my knowledge, there were never 2 run stations on the same band.
I believe there were a few instances with more than one S&P station on a band,
but not on 40.

Maybe nobody saw my question.
How are lockouts managed for 3-4 stations across the internet, to prevent
multiple stations in a M/M-D from all transmitting at once on a single band?
My concern, which seems not to be anyone elses (at least not yet), is
multiple stations on (say) 20m using a single callsign eating
up band real estate.
At a single site, they have physical lockouts (and QRM on top of that), but
across wide swaths of land in a single country
there are no QRM issues and with Internet delays (however trivial), can/are
lockouts employed?
Are multiple runners on a single band allowed in a M/M-D ?
