Alexey is working on this as a persistence alternative.


Darran, I've come around to wanting to do things as you say, but haven't 
had cycles to resurrect my server-embedded in CLI thing.

This is somewhat orthogonal to Stuart's question though, which AIUI is 
more about what configs a feature-pack should be updating. How it 
updates them is of course related though.
