Certainly nothing that is going to be quick (as counted in days). You're basically going to have to implement the network link/switch components and the coherence protocol that you wish to run on top of it. We can certainly help you along the way with pointing you at the interfaces that you need to use, but you're basically going to have to write a coherence protocol yourself (or fake it).
