I’d love (and even pay for a separate licence for) an SD “read-only” iOS / Andriod companion app that is connected to a location and traffic info service (in my case, SkyEcho 2)  or fed from the active "master" SD cockpit app in flying mode, so that I could have passengers download the proposed companion app and follow the flight in real-time, including any available traffic info. I don’t want to give passengers access to my live SD instance using my second mobile licence (that's also reserved for my backup device anyway), as they could edit or change things for the flight, my history and settings. What could an SD equivalent of https://www.foreflight.com/products/passenger/ look like, perhaps with traffic details? It could be way better!

From a commercial perspective, this could offer SD some incremental revenue and, hopefully, relatively low development costs as it’s turning off functionality from the full app. Any thoughts or similar interest out there?
