A think that an auto upadate function in CMS and player will be nice 
In our Cloud hosting CMS can be set to auto-upgrade, in the same series ie 1.8.1 -> 1.8.2, not between series ie 1.7->1.8 as that might require licence upgrades (android) and in most cases players upgrades.
Android clients can be upgraded from the CMS (requires rooted / system signed devices).
Of course I can see how auto upgrade players / CMS on the on-premise installations would be convenient and perhaps something like that might happen in the future, but there are certainly no immediate plans to do that due to various factors, even just the variety of ways the CMS / server environments are configured by different users - which requires slightly different actions to perform an upgrade.
