I'm not sure if this would be a solution for you, but you can send the OSC UDP Stream as a Broadcasting Message. Instead of the Unicast Address (e.g. 192.168.1.1 in subnet 255.255.255.0) you send it to the broadcasting Address 192.168.1.255. (If Subnet is 255.255.0.0 the Broadcast address is 192.168.255.255 accordingly).
This way the stream will be send to all IP Addresses in the same Subnet.
To separate the messages for the different clients, you could then change the OSC Addresses matching the different listeners. This way you could easily change on each device what it needs to know. Combined with a text formator actor, you could use the devices names instead of the IP Adresses and could be independent from them.
