Hi guys,
There's a python script, similar to the app_server, in the repo now through which you can forward messages to a redis node (ivy_to_redis). I used that to develop a little _javascript_ app that shows the aircraft flying around. The browser uses angularJS, which updates the visual elements automatically when you update the model. nodeJS subscribes to the redis pub/sub mechanism to get the ground.* messages and from the browser you can subscribe to any of those.
The code, in my personal public repo:
Rgds,
