Hi Marlon,
I do not know enough about low level COM (at the C level) to help write
such code, but I would be glad to help test a server you develop -- I
bet others here would as well.
Let me make sure you are aware that performing arbitrary Win32 API calls
via a COM server is possible via the PerlEval object I distribute with
the Homer script library,
http://EmpowermentZone.com/kitsetup.exe
or for a manual install
http://EmpowermentZone.com/kitsetup.zip
If one has .NET 2.0 (or above) installed, this is also possible via
IronCOM,
http://EmpowermentZone.com/comsetup.exe
