Bring back the channel object. Making a node and port on the client side was rather awkward because of the async nature of many methods. It feels better to have a specific communication channel object to interface with a server side port. Use port activate/deactivate to start/stop streams Remove links from the ports. We let other objects install a callback on the port to receive and route buffers.
