Well, the 'It worked' never appears and the cmd.Execute is
never fired, so it's still a mystery how CORBA interfaces
work. I'll see if Delphi help maybe mentions something.

I guess to get back to the Obj instance, you could let your ISomething
interface implement function Instance which returns the Obj
instance.

Be it through GUID, name or vtm.
So based on all these discussions on Corba interfaces, I can only make

There is no lookup required for this. An as cast from object to
interface is only allowed (at least in Delphi) if the compiler can
statically at compiletime determine that the type of the

No they didn't.
It was IMo cleaner (and you can mix interface types)
There are no different types of interfaces in Delphi/Kylix. Even if there
