vMotion of clustered VMs is supported in vSphere 4.1..or is it?

While looking over some of the new vSphere 4.1 documentation I noticed that VMware had updated their Setup for Failover Clustering and Microsoft Cluster Service document.  As clustering becomes a bigger component of Microsoft’s enterprise applications, support for clustering in vSphere becomes even more important. As in previous versions of this document they list the limitations for clustering on vSphere.  The list of limitation is below: The following environments and functions are not supported for MSCS setups with this release
