Render costs
Set hourly costs per render client and per render application.  View render costs of each job in real time.

Statistical data
Access a lot of statistical data via python modules to create any kind of information you need for your production. There are stat files for each client and the rrServer about all jobs that rendered.

User Approval
Pause job after a few frames or after all frames (before postscripts) and continue after user has approved the job. This way only reasonable jobs get rendered. Especially useful for cloud rendering.

Shotgun and FTrack
RR is able to connect to Shotgun and FTrack. It adds each job with render stats, preview images and quicktimes.
