Dear all.

about to load sharing DB server, 
I'd like to use facility which automatically part and execute requests from client , 
such as : update -> Master?load ->Slave.

previously,

Client ------------> Master --- Slave
   ^       update            |------- Slave
    |                              +------- Slave
    |____________________|
           load

well,  I think that I want to facility even more.
Is there useful deamon in like above situation.

1) will be supported with mysql new version (4.0 later? )

in this way,

                                       Slave <---------------------+
                                                                               |  
<update>
                                                                               | 
Client --------------------> Slave -------------------> Master
            < load/update >                   <update>    |
           <-------------------                                          | 
                    load                                                    |  <update>
                                                                               | 
                                        Slave <--------------------+

2) is there PATCH or Proxy-daemon and they are provided already?
     (e.g. thus it is  located in between JDBC and mysql-deamon.)
