Read my post from the other day. Win32::API can already do this with some runtime package namespace messing. http://perlmonks.org/?node_id=969555 I highly suggest you write an XS library though. C or C++ for your COM code.
I was thinking to add the functionality to API without the messing around part by the user since everything is already there in API to support it. Basically it would be identical to the current logic except that the DLL would be a special name (like 'NONE' - implying that the DLL is already loaded by another function) and then just using the address that would be supplied by the caller and bypassing the DLL lookup of the routine. The only non-obvious part is how to pass the address to the API module (syntax-wise) - maybe just an extra argument when the DLL is 'NONE' that contains the address of the function. Or possibly the DLL could be a ref to the address and no additional args would be needed - just check for a ref and de-ref and use it. Sounds like it would be easier to imp. than the callback logic. The idea is to not have to write any XS code to do it - just use what we have in API.
