pkgng for configuration management?

[Kamil Choudhury]

I've been setting up a private pkgng repository to push software to a family of about 20 different hosts. 

One command software deployment is pretty awesome, so I got to thinking: why not go one step further and start pushing configurations for each of these hosts via pkgng as well (either by putting the config files into the initial software pkg, or via a separate pkg that installs only the configurations)? 

Has anyone else tried going down this rabbit hole? If so, what has your experience with the system been?  

Thanks
