  Dooozer is not abandoned  There are a couple companies taking it up and collaborating on it. Last week they had a hangout and discussion on how to move forward.  ActiveState, Bitly, Soundcloud, Torbit, and the guys working on skynet are all contributing. The initial push is going to get doozer in the "ha" org to build on go. Each of the orgs I mentioned above all have their own versions that are more up to date and which have various features. We are using skynet version of doozerd internally for evaluation as a network lock service.

Notes from the meeting:

As a warning, Doozerd is basically abandoned, though it looks like someone merged a few README fixes today after a year of nothing.

My personal fav for this kind of task if Fabric + PyChef :)
