Socks5BytestreamListener are informed if a remote user wants to initiate a SOCKS5 Bytestream. Implement this interface to handle incoming SOCKS5 Bytestream requests.
There are two ways to add this listener. See {@link Socks5BytestreamManager#addIncomingBytestreamListener(BytestreamListener)} and{@link Socks5BytestreamManager#addIncomingBytestreamListener(BytestreamListener,String)} forfurther details. @author Henning Staib
