I want 1 because I want 1, I already have COM with GNATCOM, I don't need 2, but if I get 1 on Windows, it would be nice if it conformed to MSVC++/COM style VTBLs. I need to have some one reread my posts before sending for clarity, I still don't see what is difficult about the above. COM ain't Corba, COM as stated in my first ever COM announcement a year ago is over glorified OO RPC. What I am looking for is direct support of MI Interfaces in Ada, if I don't get 2 then who cares.
