I admit that the binding in its current state doesn't have much of an configuration interface to talk to ;-) It converts commands to Z-Wave serial messages and messages back to bus events and responds to config and item file changes, like any other binding indeed.

I think we need some input indeed. As to illustrate what I mean is e.g. this class: OpenHABConfigurationRecord. It describes a general type of configuration information in tree form that according to the header file is applicable to any binding inside openHAB, but it ends up in the config package of the Z-Wave binding.
