[Openstack] instance event subscription?

[Andrew Bogott]

Is there a way to subscribe to nova events so that I get notified of 
instance changes?  For example, I'd like to know when a server changes 
state from 'Build' to 'Active'.

If there isn't, would the addition of such a facility be welcome?
