AADSync - SQL Server and Domain for the service account

I would like to install AADSync BETA 3 to use a SQL Server and a domain account for the service account. I used the command line:

DirectorySyncTool.exe /sqlserver localhost /sqlserverinstance InstanceName /serviceAccountDomain AADSync /serviceAccountName AADSyncSvc /serviceAccountPassword VerySecretP@ssw0rd

REF: http://msdn.microsoft.com/en-us/library/azure/dn757602.aspx 

But I have a local SQL Express database and a local service account. Are there anything I missed?

Are there any further details on a release date for AADSync?

Thanks
