Sorry, I'm a developer and tapped that API link and the first docs page said not one word that stood out about the main questions I wanted answered: what exactly are you doing and what is the latency.
The API documentation is pretty dense! Sorry about that. To see the latency, check out: http://app.io/showcase. That's our technology in action.
We are running iOS in the cloud and streaming back graphics to the client. To get started, users upload a compiled simulator build of their app (http://docs.app.io/uploading/). It takes a few minutes. We automatically generate everything else from there.
