Open Stack

There is a new web and android interface that's being developed by
guys at Google however it's not available on our version of Gerrit.  I
think it probably won't be ready until Gerrit ver 2.13+

web interface (polymer+gerrit = polygerrit):
This interface is already very usable in Gerrit 2.12.  Currently it's
only available on the gerrit-review.googlesource.com server.  If you
like you can try it out by creating an account there and access this
new UI is "https://gerrit-review.googlesource.com/?polygerrit".  I'm
sure they would welcome your feedback.

The android interface will be announced soon it's still in early
development at this time.
