Yeah, I'm hoping that a Committer can provide some feedback on the 
direction that this patch needs to take.

One thing to consider is the pluggable storage patch, which is a lot 
more important than this patch. I don't want this patch to get in the 
way of that work, so it may have to wait a bit in order to see any new 
potential requirements.
