We tried Sequioa:
http://www.continuent.com/community/lab-projects/sequoia
We wanted automatic failover and geographical
distribution
of the database nodes. Sequoia only supports
master-master
operation if the database nodes are on the same
subnet.
We did not find anything else out there, so we wrote
our
own geographically distributed database system.
We can adapt that to your project if you are
interested.
