There are .NET interop assemblies[1], for working with Office documents, and they require Office to be installed to work. Outside of that, you're stuck rolling your own Office-document-parser.
There is a built-in "track changes" mechanism, though I don't know if all Office types handle it. Word does, at least. Though that's pretty basic.
