In COM(+): coclass == component. DLL's are simply a packaging mechanism (like jars).
This is an interesting discussion. How do people use method level transaction attributes? It seems to me that transactional attributes should be set at an interface (role) level. In other words, a logically related set of operations should have the same transaction attribute. I am wondering what sort of design wins you get with the finer grain transaction control? (other than a slight performance boost for methods that don't require transactions. In that case, I would argue that interface inheritance would be the answer.)
