A first look at possible mechanisms for handling mirrored networks
Here you'll find an example network that lets you see some of these ideas in action.
To configure locally, start the machine-grouping.toe twice so that you have two processes running simultaneously. On base_project set one project's role to be Controller and the other to be Draw.
On the Controller machine, in \base_project\base_scenes\base_scene_01 you can now change any parameter on any operator tagged with syncPars and you should see the changes reflected on the machine with the Draw role.
There are some limitations on this approach - most importantly that it only really syncs parameters and not operator locations or connections. There is a mechanism for handling re-loading changed toxes locally, but to make that work across the network correctly would take a little more fussing.
Depending on your configuration you may be able to use this to a limited degree for a show, but I wouldn't recommend this kind of approach.
