The hinting I introduced because different objects may favor different
types of connections. So does a stream object need a reliable tcp
connection and support for larger packet sizes than does e.g. a
realtime sensor input. For the latter it might not be a problem if it
loses some packages along the way if it is delivered as fast as
possible. This is known by the object and can hint the connection
mechanism. The object itself actually doesn't care how it is done, it
might use tcp because the connection mechanism finds the other end needs it, but if needed it can demand. This means objects demanding different connection types cannot connect (unless used with a converter object ?).
