bifurcation - that's interesting. That's a topic many people avoid. Thanks for bringing that up.
Look, I'm not going to get into contextual issues with bifurcation without a white board and dry-erase marker :-)
Bifurcation is splitting, fundamentally. The term is used loosely through multiple versions of Exchange. What they call bifurcation in the context of the transport/categorization engine in the latest release, was traditionally called single-instance message delivery in older versions of Exchange.
I leave this reference for you (had to go searching since you brought up bifurcation). We'll have to meet, bifurcation has a myriad of points in Exchange, dating back to 5.0/5.5 IMC/IMS - TechEd perhaps?

Thanks, I'll patiently await the response from Nick on the precise point of detachment of attachment for SIS/storage benefits :-)
