We've deployed an instance of aerogear-controller-demo with CORS support to
openshift:
http://corscontroller-aerogear.rhcloud.com/aerogear-controller-demo/
The demo is based on the latest aerogear-controller-demo
(1.0.0.M1-20121124-SNAPSHOT).
Let us know if you have any trouble or find any issues!
Thanks,
/Dan
