Client to Handle Conversation, Presence and Heartbeats

[Replicator]

@Johnny,

    Great. That is what I was looking for.
    So the model is to use a SINGLE netty client that will talk back and
forth to the alien server via different handlers. Where a single handler
would represent a single action/message of the protocol ( just to decouple
and map protocol to netty )?

Thanks for "IdleStateAwareChannelHandler" btw!
