Hi Fabien, sorry I didn't respond to this earlier as I was doing some<br>

We certainly do want to do this, although there was some concern about<br>
whether the metadata service is enabled on every OpenStack instance<br>
out there. (Also there are two different types of metadata service IIRC?)<br>
