Please try to use Interlocked* functions for ref-counting as it is 
currently a janitorial task to clean up this type of code and I don't 
think they are desparate for more work.

You leak a reference on failure here.

It is probably better to put this outside the interface declaration as 
I'm not sure if midl and widl are consistent about not outputting this 
twice.

The convention with COM interfaces is to use the CoTaskMemAlloc / 
CoTaskMemFree memory management functions instead of the Heap ones (even 
though they are the same). This is just a slight nit-pick.
