There are a great number of issues with this not yet given thought to.  
I'd suggest beginning a g.d.o page so that toughts around what needs to 
happen can easily be hashed and edited whiteboard style.  One issue 
that I haven't seen discussed is being able to determine the CVS 
version of the file that needs a difference.  You will need the 
revision number modified to determine the difference with that revision 
so that the patch can be applied cleanly.  If all files have the $Id$ 
tag the file could be filtered for the tag and the revision of the file 
expanded from it.  But what do you do with the files without the $Id$ 
tag?
