Yes, Asher is working on it this month. We've got most of the hardware
provisioned. Ryan will work on user grants when he's back. No promises
yet that we'll exceed our original deadline (which is launch of this
functionality in the first quarter of 2013) but we'll do what we can
to move it forward.

Any updates regarding the possibility to perform joins between wiki DBs and user DBs? Or wikipedia DBs and the Commons database? As it surely has been mentioned, this is a vital feature of the toolserver DB replication setup and would be much appreciated (i.e. desperately needed) on labs.
