Once we have virtualised device drivers (ie. drivers running in
isolated domains), Xen's I/O architecture will be much more flexible.
For example, you will be able to run a 'device domain' with a virtual
block-device interface to other guest OSes and which talks iscsi via a
TCP stack. 

We're aiming to implement this stuff for teh OSDI submission deadline
in the middle of May, so it's high on our priority list.
