Dave,
On PPC macs with SPDIF in (many towers and even the last PPC laptops)
the entire audio system will automatically synchronize to a valid
incoming SPDIF signal. Depending on which models are in your setup
you could send the same SPDIF signal (silence would work) to all
machines and they would stay sample locked. You could daisy chain,
although the units later in the chain might lose lock (the clock
jitter might accumulate, hop to hop). If your machines are all PPC
towers with SPDIF in and out, it might work.
The first test would only cost you one SPDIF cable. Take the two
units from your population that drift away from each other most
rapidly and see if plugging a cable from one's SPDIF out to the
other's SPDIF in fixes it.
Best Regards,
Niel Warren
