> 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}}.
