>... I know that there are plenty of camps who advocate Biz objects for this, but I'm a believer of Typed DataSets for transporting my data between front-end and back-end.

Aren't Biz Objects classes that utilize typed sets? I don't know really what a Biz Object is. In one place it's defined one way and in another the other way. With Devforce framework that I use they utilize typed sets as I see it.
