Yes.  You should be able to export anything dom0 can see as a block device to 
a guest OS.  You can use losetup to make a file look like a block device in 
dom0, then export that block device as / for a guest.

Since you can export *anything* dom0 sees as a block device, you could also 
export to domains:
* iSCSI devices imported from the network by an initiator in dom0
* NBD devices imported from the network by dom0
* LVM devices
* MD devices (software raid)
* Ramdisk (although this is arguably rather pointless)
* Any other random weird block device you have in dom0!

Cheers,
Mark
