Juregen:
Option 4 does make things easy. What happens if a particular node/variables that I2RS wants, would not normally be in the configuration? Should you configure that node in the empheral store only?

The beauty of the fourth option is that it does not require a large set of new data models. The idea is that you have a standard config data model and you use the same model for an ephemeral datastore. The server will then take the contents of the config datastore and 'merge' it with the content of any ephemeral datastores to produce what the box ends up doing (the operational state). The merging function will take priorities into account should conflicts arise.
