DII == Dynamic Invocation Interface.

Basic idea is that it allows a CORBA client to dynamically discover
new objects and their interfaces, and connect to them.

Same idea as having a LibGlade client dynamically discover new GTK
widgets and their interfaces, and then connecting to them.

Upside: It's pretty cool, and potentially makes programs more
flexible.

Downside: You have to write the client so that it knows how to
discover and use these new objects.  Suffice it to say that This Can
Get Complex.

Glad to hear it.
