I have twenty server blades which I use as Queue remotes for control by one of my P11Pro workstations. If installing P11.2 w/o serial works, that would still be an issue because of the massive chunk of hard drive occupied. Queue is tiny and the only other thing installed with it is the render engine. So, you don't need big hard drives, just lots of fast processor cores and plenty of RAM in the remotes.

There needs to be a way to install only Queue/FFRender64, and it needs to exactly match the P11.2 build number. Both my PPro2014 Game Dev and P11Pro are dead men walking, and therefore so is my network rendering capability. I'd be happy to help with beta testing for this.
Two of my workstations and one of my server blades are currently offline, but I still have two workstations and 19 server blades online.

Remote installs could be done with a Queue-only installer for remotes (matching the P11.2 build number), or as an option in the P11.2 installer such as [ ] Install only Queue for remote.

Since typed text lacks tone and expression, I'll state that I empathise with the inevitable chaos which comes with a software ownership transfer, and that I'm favorably disposed to Poser and Rendo, so I don't mean to screech. :P That said, this problem does need to be solved, particularly since there is no option to simply stay with the current Poser version. Again, I'm happy to help with beta testing.
