Yes. So that was a major annoyance, when I wrote it.
So that code is wrapped in Ted Dennisons Windows service package
that he wrote for running the SETI-client.

So a windows pc is running the OPC-server, and my service (in 6
instances, they handle ca 1600 signals).
The WMS/WCS system using this is on AIX, and it sends
commands for subsriptions to the service, which sends back
the events over socket (another protocol)

         |-----    winpc --------------|     |---- AIX --------|
PLC <->  | opc-server <-> opc-services | <-> | client programs |
         |-----------------------------|     |-----------------|


Around 2 minutes into the film, when the STV (monorail) delivers a
pallet to the conveyor, and then when the crane retrieves the pallet
from the conveyor, the above is in use.
