I cannot tell about this one. 

But generally about the diff thing:
For the teamwork plugin, I have already implemented a mechanism to highlight 
all applied hunks of a diff file in the editor, and to jump between the 
hunks. I think a similarly integrated thing would be perfect for selectively 
applying diff-files, and might be implemented without too much work based on 
the ripped kdiff3 library that's already in teamwork:

1. When opening a diff-file, you would need to see some side-panel where you 
see all the hunks. 

2. When you click a hunk, you would jump to the location of the hunk in the 
source-file, where the according text is highlighted(maybe green for applied, 
blue for not applied, and red for conflict)

3. When the cursor is within such a hunk in the source file, you could somehow 
see the alternative text for that hunk, and either apply/unapply the hunk.

For just showing a diff file, a kompare part would be just perfect.
