Is there a future proofing issue here?  Future versions of the device models 
may use a different emulated network device (e.g. there's recurrent 
discussion about whether we ought to emulate a device that will give us 
better potential for IO batching).

Guests that are deployed now may still be running on future versions of Xen 
with updated device models.

Cheers,
Mark
