Hi Greg,
<div><br>
</div>
<div>Is there any discussion so far on the scaling of VMs as in launching multiple VMs</div>
<div>for the same service. It would also have impact on the VIF scheme.</div>
<div><br>
</div>
<div>How can we plug these services into different networks - is that still being worked</div>
<div>on?</div>
<div><br>
</div>
<div>Thanks,</div>
