AH HA! I finally got it!

The trick was to use an interface with a property (as you had suggested) but
instead of returning the object or late-binding invoke to get the object, the
trick is to wrap the object in an ObjectHandle() class and unwrap it on the
receiving side.

Alternatively, I was able to return any MarshalByRef object that then in
turn exposed a property which returned the actual object I was trying to get
in the first place.
