I agree that the app should not be based on proprietary work in any way,
shape, or form save what is needed to enable users to migrate to the app.
Anyone else have thoughts on this?

Perhaps I don't have a clear grasp of what you are proposing. What I'm
thinking is that a database would be used natively, but that there would
always need to be some type of "export" function to bundle up the data
so that it could be sent to another site that doesn't have access to our
database. Whatever the format of the data bundle would be, I can't seem
to figure out a way that it would ever be entirely eliminated.
