Interface delegation is really just an optimisation and is equivalent to 
defining a set of methods to support the interface and each one then 
calls the same method in the "delegated" interface. IMHO, extending the 
definition of a property for this optimisation isn't exactly intuitive.

Delegated interfaces cause even more problems with reference counted COM 
interfaces. Unless you are really confident in your use of interfaces - 
just don't go there.
