Hi SheCurvesMobius, I resolved an similar situation with a Comau robot.
I tok a cue from a very useful example: SharedCanvasServer and SharedCanvasClient
They you can find in Examples/Library/Network
You can create one Server and many Clients do You want.
Instead the mouse coordinates You can send and receive any array data…
I have only added an simply control for right transmission ("§" + data + “#”)
I hope this simple way is useful for your case…
Keep us up to date
Regards
