Open Stack

Vish,

I miss the 'Notifications and Statistics' session. May be some of the
guys there can correct me (Jay?) if I'm wrong but we talked about:

- Extend Nova with a a server-to-server web-hook-based
publish/subscribe protocol: PubSubHubBub.
- Define a message format to describe the notification events.

Regards
Diego
