Thanks, yes, I agree. DO should only be considered for LAN operations. Apt descriptions of its limitations and implementation restrictions. We have had several 24/7 systems running, synchronized via DO since forever. It is very reliable when done right. If not, it can be a mess. > If you need a fairly painless way for network communication, I'd suggest > creating your own mechanism on top of queues of message objects and keyed, or > better secure, archiving.

Not sure what direction I’ll go at this point, but at least with the feedback I’ve gotten I can design something knowing I am not overlooking a newly introduced macOS native inter-machine RPC technology.
