I've recently taken a look at socket as part of working at ansible. 

Socket?
 
It should definitely be possible to do this (and even to use ansible playbooks to partially provision/configure the containers.  However you would need to have someone updating the images periodically just like you presently need to update the virtual machines you maintain.
 
Yes.  There is no free lunch =)  We need better tools in this area.  If anyone's interested, I'm trying to centralize some RPM-based-distribution + Docker discussion on projectatomic.io, e.g.:

It would probably be best to have the whole sysadmin team become somewhat versed in docker usage (to the same extent as they're aware of virtual machines at least).  There isn't a whole lot to learn for basic proficiency, though, so this wouldn't take too long.  If you don't want to train everyone, having a docker czar and a couple helpers would be enough to actually do the work.

Yeah, the plus side is it is very easy to get started.
