The only one I'm aware of (and it's been a while since I've seen/used 
it) is an add-on to MS Project called ProChain, developed by (IIRC) Rob 
Newbold, a very knowleadgable person on the theory of the whole thing, 
but it was very hackish. I've always dreamed of creating one, but it 
would require time/effort. As I said before, maybe next time I'm doing 
heavy PMing (currently I only need to PM myself, so  I'm the only 
resource available).
