While the road to release has not been as smooth as I would have liked (down to me in parts :-) ) , we have finally published the early adopter version on OTN.
We very much welcome your feedback on it. Our plans is to have this as a standard feature of Oracle APEX 3.0, so you have the chance of your feedback making a difference in the final product in a short timeframe. I look forward to receving your feedback and making the product better because of it.
You will find more details about it here.
