/Ideally/, I'd want an article to appear in multiple groups, eg:

Bob Smith
   Article A
   Article B (with Fred Bloggs)
   Article C

Fred Blogs
   Article B (with Bob Smith)
   Article D

etc...

Well, I've got 2000-3000 new articles coming in each day, so yeah, there 
probably would be some incrememtal updating involved :-(
I need to update 1000-2000 authors per day, I'd guess. Which might not 
be so bad.
Worth trying, anyway.
