	I had to use a separate "ikernel.tlb" to get Wine to read the type
information. It couldn't get it from the ikernel.exe because I think
it's encoded somehow (unicode, MultiByte??). It doesn't have the magic
MSFT as the first four bytes.. Wine seems to read all the type
information correctly ..


	So then in CoGetClassObject you would create and return a dummy object
that would act like the actual interface the program is looking for.
Then the dummy object would accept parameters, do the marshaling, and
make the IPC request to the Local Server?
