I don't know if anyone has implemented this yet at all, but if anyone is interested I have a Hyper-V Production Cluster (which supports live migration) running with two Server 2008 R2 nodes. I know at least a couple people asked me about it but I can't remember who they were. So if anyone wants to share notes, just let me know ;) Ehren J.
