It seems to me that SQLite and this .NET hierarchy are both trying to do essentially the same thing, which is allow you to store heterogeneous data in a single file. If you want to use SQLite for part of that, why not use it for *all* of that? What is it that you want to store in System.IO.Packaging.Package that can?t live in a SQLite table instead?
