A group of sibling resolvers might want to exchange information about 
the contents of their respective caches. Caches of DNS data and caches 
of web content aren't too different, if you're looking from a 
sufficiently high altitude. I can't picture how this would work in a 
transparent fashion using a WCCP implementation on a router, but it 
seems possible that elements of the protocol might be useful between 
individual unbound instances.

(I'm not saying that I think does or should implement WCCP; but it does 
feel like the kind of crazy thing NLNet Labs /might/ have thought about
