Well Derik pointed out the problem with the previous simple
approach. So how about this one.

DH can be used with multiple users, where each passees eack other 
part of the key. What if a four way exchange was
used where the client in effect is two of the parties, and the
KDC is the other two. Only some of the traffic is exposed. 

I have not worked this all out, and it might just degrade 
into the same problem as before. 

Any thoughts on this?
