Yes, if you got synchronization problem that Paxos can resolve,
leveraging ZooKeeper is a good idea IMHO.
Depending _always_ on ZooKeeper is maybe not the best call, that's why
I've got on my mind to propose a library in Oslo providing several
drivers solving this synchronization issue. Where one of the driver
could be ZK based.

As for MySQL, let be reassured, it's not needed, you can use PostgreSQL.
