Please read the links I sent, and add this one :

http://dev.mysql.com/doc/mysql/en/mysql-cluster-overview.html

I'm talking about pure active-active cluster. This setup could be strenghted

between Applications and SQL. About the link above, note that mysqld server
and nbdd server can be on the same machine.
