Thanks. There is no reason the XCP driver could not do the same, right?
Shared disks would still be "unsupported" but it would just work on a 
single physical node.
I think the configuration is useful to train/demo/play around with 
Windows configurations requiring shared disks.
Oracle RAC, Fail-over clustering to name a few.
Even a single node cluster is a valid configuration for learning.
