I'll give it a go:

1) Somebody writes a corba object which references some backing store. 
This object supports (i.e. derives from) the gnomeAddress interface.

2) The object is 'registered' with the interface repository.

3) The client address book program knows about the gnomeAddress
interface, and queries the interface repository (for the Interface
Repository is a standard corba object as well, and thus can be used by
any corba clients) for objects that support it. It returns a selection
of objects to the user, and the user chooses which object to use.

4) The client then talks happily to the corba object, calling functions
on it to retrieve and save new addresses to the backing store
encapsulated by it.

5) The world is a wonderful place, all thanks to the fact that gnome
developers have the insight to write corba interfaces to their programs.
- hurrah!!

Hope that helps,

Phil
