I think you can use the CollapseFilter to collapse on "version" field. However, I think you need to modify the CollapseFilter code to sort by "version" and get the latest version returned.
Ooo, that's very cool. I assume the patches haven't actually been applied yet? This would let me just collapse on the name field and if I could get it to sort by modification date before collapsing it'd be perfect.
I have a feeling I'm going to wind up extremely lost, but I'll delve into the patch and see what I can find.
