[Samba] Samba 4 Clustering

The first link appears to only allow for failover at the server side for samba. Heartbeat is OpenSourcethat does this for multiple platforms. While this is A Good Thing, the issue is one of state vis-à-vis the client's connection(s).
The second link appears (or I missed something) to only discuss NFS.
As can be read in the Samba documentation, SMB/CIFS state is what prevents truly seamless and transparent failover. While Heartbeat will function excellently to provide HA for multiple samba servers, in-progress client connections will be hosed, and there appears to be no easy way around this, as it is inherent in the protocol.
