I think it would have very little chance of being accepted upstream.  The xway 
TCP-over-Xen implementation would have even less chance of being accepted *as 
is* due to making modifications to the Linux network stack.

Yep.  If a generic solution using something like virtio is available *and* 
there are multiple hypervisors which can leverage it then hopefully it would 
have a decent chance of being included.
