A preview release is being published to Splunkbase in the next day or so (URL pending). Follow instructions to be considered for the beta. Thanks for your interest!
We will have a closed beta followed by an open one. Existing customers should let their Splunk SE or Account Manager know of their interest, but trust me, we know there is much demand! Thanks everyone for your patience thus far.
This is a very popular app and we know you guys are excited to lay hands on it! We are working as fast as we can to get out a quality product. Sorry for the delay.
I am also awaiting this app. I was under the impression from what I heard at .conf2012 that this was already released.
Any word on when it will be available would be greatly appreciated.
