See it like this: An interface is a fragment of VMT. All methods of the 
interface are there in order.

If implemented right, it is like a pointer into the implementing 
classes' VMT table.

The IVT is a mapping of interface identifiers (in COM terms, GUIDS) 
mapped to the offset into the VMT they apply too.
