I guess to get back to the Obj instance, you could let your ISomething
interface implement "function Instance" which returns the Obj
instance.  That's a old trick used in Delphi code with COM interfaces.

Well in that case, shouldn't the compiler give me a error when I use
Corba interfaces and try and use the Supports() method.  That would be
the logical thing wouldn't it, since Supports() would then *never*
work with true CORBA interfaces.  Don't give the clueless developer
false hope. :-)
