[DCP-o-matic] How many encoding servers?

Hello all. I'm doing tech on the London Short Film Festival which is January. We are delivering all the films to cinemas on DCP this year (all 350 of them) and will be using DCP-o-matic to use them. We're holding a workshop tomorrow and Sunday where we're going to train 100 film-makers on DCP-o-matic, and then guide them through the process so that by the end of the weekend, they will hopefully all have DCPs of their films. I have a couple of last-minute questions that I would very much appreciate it if anyone would be able to help with. _1. Encoding servers_ We have a network of 30 iMacs, all networked together with Gigabit ethernet. We intend to run dcpomatic_server_cli on all of those, with DCP-o-matic itself running on the laptops of the film-makers and using the encoding servers to do the heavy lifting. a. Will it work with 30 encoding servers? b. What happens if two instances of DCP-o-matic try to send jobs to the encoding servers simultaneously? Is it first-come-first-served and whoever submits their job first gets control of all the encoding servers until their job is complete? Or do the encoding servers get shared out between different jobs so multiple jobs can run concurrently? Or, terror-of-terrors, will the whole thing crash? _2. Best version to use_ How stable is v1.76.13 likely to be? Or should we use v1.76.0? I've been told that some issues with colour space conversion are being resolved in recent test releases. Is v1.76.13 going to give a better result in terms of colour than the 1.76stable? Sorry for the barrage of last-minute queries. I hope someone may have some pointers? Many thanks, Jim
