Open Stack

I second this. We build web applications for the Foundation that run on 
OpenStack instances. By and large, we have no need to touch the 
OpenStack API. However, we rely on  OpenStack for our infrastructure. 
This is, IMO, a very big potential market and something that we should 
be sure to include. If not in this WG, then some other.

Cheers!
