Thanks to Dugie for the tip (once again!) here are a few more papers you may enjoy (it's good to see his recent 30 hour flight there and back to Seattle haven't done him in).
Virtualization.info picked up on these whitepapers - they also speculated on what might be announced at MMS...I wonder :-)
You can search for the sessions and the content here:
