Octane is 100% compatible with Backburner to send to a render farm. We use it for all our projects. Do your project, Send to backburner...and whatever computers are hooked up on your farm (that have octane licenses) will render the project.
The only thing to beware of is machines that have different video cards will render out differently. Some brighter and some darker. Only buy the same video cards, I am not aware of a workaround or fix for this.
