Rex,
I have a technique I've been brewing up just for this purpose that I'll share with you via private e-mail. After it's ironed out, I'll post it here publicly for the benefit of all. Basically, it involves a new property on KBizObj that lets you specify whether the business object should use a private or default data session.
This property can be set when you drop a business object on a form at design time. It could also be set dynamically by passing a value to a business object in its Init().
