This is a good start to play around with the galera multi-master mysql synchronous replication (http://www.codership.com/products/mysql_galera)
HOWTO:
* play around (add a database and data, chaos-monkey nodes etc.)
WARNING
Change the mysql root password in production and limit access to galera cluster members!
TODO
* naming: master -> donor
* put a load balancer in front of the cluster
* make cluster "masterless"
