Upon reading, it would seem that you only need ARC Welder if your app needs to rely on Google Services. I am defintely not sure it is the case of Xibo, though not tested. Also, there seems to be an easier way to download Google Services: install a regular play store ported Android app, prior to installing Xibo, which will download the needed software. You'll still need to repackage the app for Chrome OS.
Anyone with a Chrome device and half an hour to test?
Also: What other MdM/device management options would you advise for DS application?
I read about MokiMobility online, definetly not open source and no public pricing, then the fleet of generic commercial MDMs.
Then there is WSO2, but it doesn't seem much fit.
Or you manage them all by hand under VNC, which you might eventually need to remote reconfigure XFA if needed.
Anyway, it seems that apart from ChromeOS, you can kiss operating system updates goodbye.
So... Has anyone any idea about how to best manage your Xibo player fleet?
Can you create XFA config files that you could push to your players (by uploading them to a folder), instead of having to remotely reconfigure them if needed?
