We have a tool that displays what all of these are and what capabilties they support. Should be released in the next week or so. All the vid does is map to an existing set of metadata that allows display in the new app. Porting the VID from an existing device will allow you to take any device with a standard set of compatible capabilties and get it up and running in the new UI. Further out we are going to release a tool that will allow you to generate your own custom capabilties and describe how they will be displayed in the new UI. Custom capability generation should come around March-April time frame to some device developers in the community. That said, none of these options are going to allow an approximation of the old ui where you could render any sort of html display. For really custom UI we are developing something else and that is too far out to talk about at this point.
All that said. Tools are coming.
