You could do that, or you could keep an index of CLSIDs (and the DLLs to
load them) elsewhere. In Windows/COM, these live in registry under
HKEY_CLASSES_ROOT\CLSID. When you CoCreate an object, the OS finds it's DLL
via a registry lookup, loads the DLL, then calls DllGetClassObject to get a
factory.
I think we would omit the registry part and put the CLSIDs in meta-data.
