Alan,

>The question has come up here several times about using MM without actually having a database backing it up. One example is an application that scans a directory structure, retains file and folder info, and then displays that info in different ways. The info may then be persisted in a form other than a database, perhaps an XML or just a comma delimited file.

I'd like to know a little more about the sort of things you were trying to do with the business objects and what issues you ran into. Why don't you contact me via private e-mail and we'll talk!
