Just an update - and in case it is useful to any noble Wine hackers out
there for some reason :-) we eventually implemented COLEAT:
based on your advice, and a chunk more research - that lets us trace
OLE automation in its several forms: even pre-compiled VB6 executables'
usage - such that we can create COM interoperability APIs for Collabora
Office / LibreOffice.
We used IAT patching in the end to inject our tracing proxies, and of
course - all patches most welcome.
Thanks for the pointers,
