I am thinking about getting some commentaries that run on the Libronix platform - WBC, BEC, etc. They are not cheap, so if I could get some feedback on interop before I spend the bucks, it would be great!

It looks extremely easy to add synchronization between BW a Libronix commentary using the libronix hyperlink protocol. That may serve all my needs.

However, I would like to ask about driving Libronix via the object model.

Has anyone written to the Libronix automation interfaces extensively (or retreived their typelib information)? How much of the Libronix functionality does the automation interface expose to external clients?
