Hi there @jrhooker,
You can either use OSC (OpenSourceControl) for this or use our Net Broadcaster / Listener actors.
OSC will need a dedicated IP. Yes, in performance/installation environments we typically set static IPs in the DHCP lease of the Router, that way when we connect a device with a specific MAC address it will always link up with that IP address.
Net Broadcaster is great because you simply set the ID of the computer in the Isadora preferences menu. You don't have to set the Network IP address. Just plug all your devices in with the same router and you are ready to go, set your Network ID in the Isadora preferences so that they all have a unique ID and you are ready to go!
Net Broadcaster requires a router with Multicast support.
