QCAR Extension, min supporting license requirements?

What’s the minimum licensing bundle necessary to support the QCAR extension?

Is this supported by Unity + Android Pro, or only Unity Pro + Android Pro?

Also how can we obtain a trial to evaluate the QCAR extension?
Does the Unity 3.1 Full Version trial include the necessary Android components?

we don’t provide android basic yet, so only Unity Pro + Android Pro would go.
please email me to oleg@unity3d.com to get the trial
