I have used OSC for this purpose between two MBPs, and also over the last year relied more heavily on the QLab Widget controller. Neither of these guarantee frame accurate synchronization between the systems, but should be pretty close if the systems used are similar.

Hello folks
It's important to understand the potential implications of the way your redundant setup is arranged. In the case of OSC being sent from the main Mac to the backup, you're potentially setting yourself up for a problem: since the main Mac directly influences the backup Mac, failures on the main can cause failures on the backup.
The Widgeteering controller, as well as the Go Box 6 (which I design and manufacture, entirely separately from Figure 53), sends independent signals to each Mac, which minimizes the possibility of "cross contamination" if something goes wrong on one of the Macs.

Just to echo Sam, I would say one of the easiest and most reliable ways to run a redundant system is to use a simple QLab remote, MIDI or otherwise, that connects to both computers. Run each computer to a separate sound card, and switch between A and B on the mixer. Of if you're doing video, run both computers into a simple switcher and use the switcher to switch them.

Also if you use Qlab to control an external app or devices that controls light, use a DMX merger to switch from the main DMX input to the backup one.

I've synced to machines running the same workspace with a midi controller that has 2 outputs: one USB, and one 5 pin din adapted to USB.
I've also slaved one to the other using IAC Midi over ethernet - but as mentioned before that makes it all dependent on one machine still.

We're using an iConnect interface to split the midi commands for two mac minis. It's not frame accurate, but is in tempo, which is more than enough when the poo hits the fan.

type of setup limits the number of failures that your redundant system
can solve. Specifically, if there's a problem with the iConnectivity
interface, then both the main and backup Macs will immediately have the
same failure.
Only by having completely separate main and backup systems can you truly
ensure that a failure of your main system will not cause a failure of
your backup system.

This product seems to be very ideal. I just ordered one now.
