If anyone is interested - this was my suggestion to Tim

my thoughts would be to program using presets and cue list on the main machine, then zip up the show file. Copy this onto the second machine you have and ensure both are on the same network.

On the second machine, turn on "Send Remote Preset Commands" from the Remote options in the Catalyst Control window, and "Accept Remote Preset Commands" on the main machine.

You can then run the cue list to trigger presets on the second machine, this should send remote preset triggers to your main machine.

I hope this is clear - if not - please email me.
