Sorry to not respond sooner on this. We've been heads down on development. As you noticed, ORBX is now shipping inside Autodesk remote for PC and iOS. ORBX.js (for HTML5) is coming along very nicely and should be in developers and users hands before the end of the year. We're currently validating IE11, and once that is done, we'll be able to confirm full support on all 5 major browsers, which is a key milestone prior to release. There will be documentation and developer resources on the release of ORBX.js to developers. It is meant to be simple to use with minimal if any setup required to get it up and running for an app, live video or game.
Thank you for your patience.
