Lets say we have pc <> switch <> lots of network boards for a single mic
PC could broadcast the clock to all micboards and the would hopefully
arrive without noticeable skew or jitter. And the micboards could
answer with that timestamp and the converted value. In this case
the PC requests each sample one at a time from all micboards.
Would that be good scheme?
A simple ping here, has a rund trip time of 0.25 to 0.8 ms depending
on end equipment.
