Hello,
I would agree that TN is not directly needed. I would add that even with flat files, you can have a database entry for the contents instead of having them through out the filesystem. I would say that, for an easy way of setting up a logged view of guaranteed delivery for things like possible ftp of files, the TN would be nice. You can still duplicate (theoretical bad thing at times if you already TN) the logic for viewing information in TN with a subset of database tables to see things like services that conclude success on retrieval and deposition of documents and the repository of persisted transaction documents to be part of the exchange.
