Might be up for debate or just plain wrong. Just some notes I scribbled down some time ago.

Please correct me if wrong, but judging only from current Akka (2.3.0) documentation examples ConsistentHashing Router doesn't seem to match Content-Based Router pattern. CHR in Akka is more like partitioning to worker actors all with same behavior, where in CBR routees/endpoints/workers are different, with different logic/behavior.
IMO closer to CBR is plain Actor, with conditional pattern matching; downside is that Router Actor is tightly coupled to routees/endpoints/workers.

Any chance for an update including Akka-Stream?
