I've added SAX parsers for pptx and docx over on Apache Tika. These rely on POI for OPCPackage, a bunch of other classes and overall design.
I've thought about moving that code into POI, but I haven't found the time or need, and the code is my typical kludgy-mess...and I don't want to pollute POI any more than I have. Take a look over on Tika and see if those will work for you. Let me know what you think...
