No problem -- I just wanted to make sure I was understanding you.

I'm not sure I follow. If you have a linux compatible library for reading OLE
Compound Documents, there should be some class corresponding to IStream. If
you're trying to implement OLE Compound Document support from scratch, it sounds
like a big job and I can't help you much. In my experience, microsoft file
formats are very poorly documented.

The library needs to be cleaned up a lot before I can post it. If there is
sufficient interest, I'll try to do it, but it would be at least a couple months
from now, since I'll be busy trying to get iostreams ready for 1.33.
