ChannelReceiver Interface
The ChannelSender interface is the data sender component at the bottom layer, the IO layer (for layers see the javadoc for the Channel interface).
The channel sender must support "silent" members, ie, be able to send a message to a member that is not in the membership, but is part of the destination parameter
