-1) Adapter concept thingy
-
- Needs a name and index
- Current IP address etc
- interface_info
-
- Must be able to get one from an adapter index or name
- Must query the ip address and such
- Must be able to set the address
-
-2) System state doodad
-
- List of adapters
- List of parameter changes
- List of persistent stuff
-
- Must be able to initialize from the registry
- (persistent stuff, some adapter info)
- Save changes to persistent set
-
-3) Parameter change set
-
- TODO
-
-4) Persistent queries

- *
