So, my implementation of ref-counted using CORBA will be equal to TInterfaceObject, but I have to call _AddRef/_Release explicitly. Ok, that is not a problem... a little less magic, but works ;-) >> You're right. >> So, if my code will have compatibility with Delphi, is better to use >> CORBA interfaces and no reference counted if I compile it on Delhi.

COM interfaces is to use in Windows, AFAIK. I don't think using COM is the better way to use interfaces in FPC, so you too. To FPC I choose CORBA and instances of class variables and to compile in Delphi something like tnullinterfacedobject. ;-) Thank you very much.
