OK, that's easy
Hijack the space bar by deselecting it in settings/keymap

Create a new cuelist called HijackGo (or anything else you like)
Put a fire all group into this list with 2 Network cues
The first network cue sends this to your remote machine patch
/cue/#/cue/selected/number#/start
The second sends this to your local machine patch
/go

Example workspace attached. In this workspace, settings/network has patch 2 set up for remoteMachine with localhost port 8001 so I could test on a single machine. You will want to set it with the IP address of the remote computer on port 53000.
