* A source of input and output streams for use with stream-based
* TransportLayers. Implementations should contain the
* necessary information for reconnecting streams as necessary. For
* example a ServerSocket-based implementation should be able to listen
* for fresh connections and get new streams from them (this must be
* done when refresh() is called).
