Pluto Docker on different (Unraid) server? (and other questions)

Is it possible to run the Pluto TV Docker on a different server from the Channels DVR server? I currently have this working while running both on a Windows 10 Pro PC. I just built an Unraid server using old hardware and wanted to try moving the Pluto Docker there.

I am considering building an upgraded Unraid server to run the Channels DVR docker as well. My dream would be to have a single home server for files, Channels DVR, (perhaps SageTV DVR as a backup) and an iTunes server for the house. I currently now have 4 server PCs running Unraid (new), WHS 2011, SageTV and Channels DVR each on a separate machine (each with fairly old motherboards/cpus). Thanks for any input or suggestions.

Of course. Just point your Channels DVR server to the IP of the device running Docker, making sure you use the correct port that you are publishing through.
