Not a big deal, I have some cool stuff open source stuff in HP I’m moving on to
which I’m excited about and can help Openstack in other ways. You should hear
about that in a few months time.

Yes, sorry, got back from Seattle a couple of days ago and am extremely jet
lagged :)

No one else runs it in production that I know about, but there are several
trying it out and appearing to want to contribute.

I don’t know if we pre-dated the planning phase, judging by a later email on
this thread our planning phases were at the same time. I wasn’t a big part of
the planning phase so it is difficult to comment there. But we had something
we could use before we were in a place where we could even try out Neutron.
Also to start with our API was Java based (a Python replacement came later).

I’m not sure what is public and what isn’t so I won’t name names. They are
currently talking to us about the best ways of working with us. Both companies
want to use Libra in different and interesting ways. They are not currently
deploying it but are both playing with it. It is early days, they both
approached us just before the Christmas break.
We know that working with the wider community with Libra has not been our
strong point. It is something I want the team to rectify and they are showing
signs of making that happen. People that are interested in Libra are welcome
to hang out in the #stackforge-libra IRC channel to talk to us.
