Unless you are well versed with interfaces, I would not go there. Mixing
object references and interface references (especially if reference
counting is enabled) - you are bound to run into trouble.

None of the Windows'ism like COM's IUnknown, or Delphi's IInterface
(alias to IUnknown) on any non-Windows platforms.

Then stick with Delphi (Windows COM style) interfaces. I don't believe
Delphi support any other style of interface (eg: CORBA, XPCOM etc).
