> Encapsulate connections to peers into the {{Peer}} and {{PeerServer}}
> classes. Since many Java classes may be involved with these connections, it
> makes sense to create a container for them. For example, a connection to a
> peer may have an input stream, output stream, readablebytechannel, encrypted
> output stream, and encrypted input stream associated with it.
> This makes us less dependent on the {{NetUtils}} methods which use
> {{instanceof}} to manipulate socket and stream states based on the runtime
> type. it also paves the way to introduce UNIX domain sockets which don't
> inherit from {{java.net.Socket}}.
