SQLite with NFS + cachefilesd
EBS's multi-attach doesn't support I/O fencing, meaning I'd expect putting an application that isn't aware of what's happening with such a volume on it to encounter issues.  (And given my luck, I'd expect those issues to first happen a month after I've gone live during my first big burst of business)

It also doesn't help you if there's an issue with the volume.

If you really need no downtime, is there some reason you're not using RDS or some other service that has failover support, mutli-AZ support, and is just generally meant to be used in a scenario like this?
