Current obstacles:
- webxdc apps have no way to request permissions, see Allow access to camera, geolocation, other Web APIs
- webxdc apps cannot run in background on Android. See another app prototype that would benefit from the background thing: I made a video call app (WITHOUT 15-second ping this time). But TBH I’m not even sure if this is possible. I do not recall a video calling app that can work in a browser in the background.
