This blog post speaks briefly about colocation, and how this can be achieved using AtomicMaps.

> Need to build a mechanism in which L1 invalidation is NOT multicast, but instead is unicast _if necessary_ to specific nodes that may have cached a given entry.  This can be detected by maintaining a list of nodes who have requested a key via a remote get, but this would need to be relayed by all data owners.
> Benefits would be performance by removing unnecessary invalidation where this is not needed, and by reducing noise in network stacks of most nodes.
