> We currently use TCP server and client sockets to transfer state with STREAMING_STATE_TRANSFER. Add an option to use the default transport (could be TCP, could be UDP).
> State provider:
> - Write state into an output stream
> - The output stream generates unicast messages of a fixed size and sends them to the state receiver 
> State receiver:
> - Provides an input stream
> - The app reads data off of that stream
> - The received message chunks are placed into the input stream
> Might be more firewall friendly and causes less config overhead (e.g. punching of holes for the TCP conn in the FW).
