It is ambiguous. Some COM forms can be queried for their methods etc, but in
some cases straight interface use is also possible.
But my guess is that it is like DirectX, import the typelib, generate the
interface units for it, and go.

Usually scripting and non scripting interfaces are separate. (since they
derive from different base interfaces)

A typelib importer is already in svn.
