> Gossip has CRDT support. This is an important building block to doing higher 
> level things. The next piece is being able to act on an object when we 
> receive it. For example lets take the most simple case. I want the cluster to 
> vote on something such as "who asked for this lock first". Currently we 
> replicate objects lazily through a thread, what we want to do is on reception 
> of an object apply some function such that we can modify the object being 
> received.
> The way I want to go about this is voting objects can be injected with a type 
> like VoteContext
> http://stackoverflow.com/questions/27133161/how-to-pass-constructors-parameters-with-jackson
>   
> Users can register Voter implementations. On receiving an object  the 
> interface allows logic to be run. In the case of a Voting each node appends 
> its vote as the object moves around over time you can poll your local copy 
> and determine the result of the vote.
